Right before the SXSW festival in Austin, Texas a couple weeks ago, some of you may have read about SimpleGeo’s awesome location data visualization tool called Vicarious.ly. The site showed location information coming in to SimpleGeo from Austin in realtime, and included elements such as Foursquare check-ins, Gowalla check-ins, geotagged pictures from Flickr, and geotagged tweets from Twitter. It was really interesting to watch in realtime, but it may be even more interesting in hindsight. Luckily, SimpleGeo has released a video to show the data over the span of just about a week (March 11 to March 17).

As you can see, Foursquare and Gowalla clearly dominate the data. This is in line with what we heard in the midst of the so-called “location war” between the two. It’s also kind of fun to watch the early hours of the morning when everyone is clearly asleep, and then watch as the data comes roaring back to life around 8 AM as festival-goers undoubtedly nursed hangovers to head to the convention center.

When bashing AT&T’s network, two cities usually come up above all others: New York City and San Francisco. AT&T has even acknowledged just how bad it is in those cities. But they’ve also said for a while that they’re working on making it better. And apparently now that work is far enough along that they’re emailing customers about it.

Over the past week, AT&T has been emailing its customers in San Francisco to let them know that the network is getting better. “We wanted you to be among the first to know! We recently enhanced the 3G network in the greater San Francisco area to provide better in-building 3G coverage, fewer dropped calls and a better overall wireless experience,” says the email.

It continues, “With better coverage on the nation’s fastest 3G network, there’s never been a better time to be an AT&T customer.” In other words, “things are getting better, please don’t leave.”

Hopefully, it’s a good sign if AT&T feels comfortable enough about its network to email its customers. Another good sign: AT&T did a great job this past week keeping its network stable during the SXSW festival (after failing badly last year). Still, AT&T has been saying for a while that they’re working on fixing the network in San Francisco, and on any given day it can be as bad as ever.

Below, find the full email being sent:

We wanted you to be among the first to know! We recently enhanced the 3G network in the greater San Francisco area to provide better in-building 3G coverage, fewer dropped calls and a better overall wireless experience.

The great news is coverage in Northern California will continue to improve as we expand capacity, optimize and add more sites in the coming months.

With better coverage on the nation’s fastest 3G network, there’s never been a better time to be an AT&T customer.

We thank you for your continued loyalty and look forward to sharing more good news soon.

Today, during his keynote address at the SXSW festival in Austin, Texas, Spotify CEO Daniel Ek had a big revelation: “On certain days, we’re consuming more Internet capacity than Sweden has as a country.”

Ek made the statement when asked why Spotify chose to use a P2P model, rather than centrally store all of its music in one place and stream it from there. Ek noted that if they were to stream from one UK datacenter, they’d consume all the bandwidth. So instead, they leverage the power of the Internet to get their users to help them stream to other users.

Ek also said this was primarily the reason that Spotify is a native application, rather than a web app. P2P streaming is a bit more complicated than streaming from one source on the backend of things, obviously.

When asked why Apple (which of course, runs the largest music store in the world, iTunes) doesn’t use the P2P method, Ek said that was the “million dollar question.” He then speculated that they will move more towards Spotify in terms of being in the cloud (something we’ve written about a few times), and having a subscription model.

Ek noted that Spotify is now in six countries and has over 320,000 paid subscribers. That’s up from 260,000 the last time they mentioned it. Overall, they have some 7 million users now. And yes, that’s largely without the U.S. where the service only exists in a very limited closed beta as the company negotiates with the labels for music rights.

We’re here at the SXSW festival in Austin, Texas where Twitter co-founder Evan Williams doing a keynote Q&A with Umair Haque. Williams may use the time to talk a bit about Twitter’s upcoming ad platform. Update: It’s actually an “At Platform” called At Anywhere — more here.

Interestingly enough, Twitter saw its first burst of popularity three years ago at this very conference.

Below find my live notes (paraphrased):

UH: Ev you have something pretty interesting you want to say today?

EW: Yeah, we want to announce something. We wanted to announce our new “At Platform” (undoubtedly to be spelled an @ Platform) – a way to integrate Twitter into any website. “At Anywhere” – basically this allows you to place the Twitter hovercards on any site. We have 13 sites we’re launching with including Amazon, ebay, Yahoo, Digg, Bing, Meebo, Salesforce.

UH: So what can you do with this?

EW: You can easily tweet from any page that is using this. Also, maybe you want talk to authors of posts without going to Twitter itself, you can just hover over their name and tweet them. Twitter is a very easy way to keep in touch.

UH: So this helps you contextualize information. But why would sites use this?

EW: A connection to users you didn’t have before – and it keeps people coming back. And it will result in more followers for a site. Also, hopefully more people who are your fans using twitter to talk about you or your content. And you can bring in users’ tweets talking about your site.

UH: So it’s a platform to juice up site’s networks and virility. But it’s an “At Platform” not an “Ad Platform”.

EW: Yeah, it’s about lowering the barrier for information.

UH: What makes 21st century businesses different? Like Twitter? The first principle to me is experimentation. Why are you willing to explore different possibilities?

EW: Experimentation lets you create value. “Whatever you assume when you start out, you’re wrong.” Most of the great businesses of our time have experimented. Like Google.

UH: So it’s about creating value, then figuring it out?

EW: Yes, it’s about creating experience for users and businesses. There is a ton of business use on Twitter today — it’s one of the biggest uses. We want to make that better, easier, faster.

UH: What is Twitter evolving to?

EW: What is Twitter has always been a tough question to answer. We think of it as an information network — different from a social network. It’s about getting info and also sharing. You can take advantage of Twitter without sharing anything about your life. We need to increase the signal-to-noise ratio.

UH: So better information, better connections, better choices.

EW: Yes.

UH: Experimentation is about iteration. So how does that happen at Twitter?

EW: We have a bunch of awesome people in the company now. We’ve grown very quickly over the past year. Our employee growth curve is almost like our user growth curve now. We have people on focused teams, like mobile, or internationalization. We’re worried about central thinking and slow processes. So we tell our teams to “go for it.”

UH: So what’s your role?

EW: I don’t get into the nuts and bolts of code, cause things would be a big mess. I spend most of my time thinking about the high level issues. And I think a lot about the company – how do we scale the company, about our culture, etc. How do we define the characteristics we want. I think there is a parallel between the service and the company — openness is huge, transparency.

UH: So openness is very important. Help us trace the arc of openness at Twitter.

EW: Yeah, it means a lot of things. We debated if openness or transparency. “A window is transparent, but a door is open.” The users have taken Twitter and morphed it into what they want it to be. Now developers are doing the same thing. Openness is really a survival technique.

I sit down with new employees when they start and go over 9 assumptions you should have about working at Twitter. One key one is assume there are more smart people outside the company than insides.

UH: What about giving the golden goose away? Why be so open?

EW: That was a big question for us – the deals with Bing and Google. These were the first guys we shared our full stream with. There’s a lot of debate about that. Because we don’t have a business model yet, so why give it away? But we went back to the principle of giving users the most value.

There are 50 million tweets a day, how do we show you the best ones for you? Right now, we don’t do a good enough job of that. But with these partnerships, we have more chances to do that.

UH: Was there a lot of internal debate about this?

EW: Yeah, there was a ton. But we decided it was good. And now we’ve expanded the deals – like with Yahoo. And a few weeks ago we talked about giving this data to thousands of others.

Now third party developers are building a lot of value. Like adding pictures to Twitter.

CoTweet and HootSuite are really interesting too. Twitter.com isn’t a good interface for doing customer support, but those guys are. CoTweet just got acquired by a company that wants to focus on that more.

We’d love to see much more focus on creating these deep experiences that create value.

UH: So experimentation and openness. Other companies want control, like Apple. How open are you guys?

EW: We’re pretty open – there is some control we need to employ because if we were infinitely open we’d be doing a disservice to users. Openness can work against you still. It has to be managed a lot. Having an open API makes it easier to make apps that will spam users. We send cease and desists everyday to companies making spam tools. We have to exert some control.

UH: I think shepherding is a good way to put it. So you had some interesting use recently – such as the earthquake in Chile.

EW: I got an email recently about the earthquake, thanking us for helping with the situation. This is very gratifying for us because we’ve always held it important for Twitter to reach the weakest signals in the world. We started out with a big focus on SMS – and it’s still really important to us. Because it reaches so many people. We have deals with 65 carriers around the world to send these SMS tweets.

We’re at the beginning. We’re seeing really strong growth in India where SMS is huge. And in the Middle East.

UH: I think this changing the world stuff is the future for entrepreneurs. It gets to the heart of the point about inclusiveness. So – what is an “active user”?

EW: To me it comes back to – is someone getting value out of Twitter? If they don’t have an account it’s hard to know, like people who search Google for tweets. In the beginning we put a lot of focus on telling the world or your friends and family what you’re doing. But now there is something interesting on Twitter for everyone – like the Flaming Lips being on Twitter, you can get updates on the band.

And as more people start getting information on Twitter, they’re more likely to get involved.

UH: Someone has started using Twitter inside the White House, right?

EW: Yeah, it’s really interesting that it’s from in the White House. It’s an official channel, but they’re using it a different type of way. It’s about reducing the walls between people with a lot of influence, and those who they influence. And that’s the most profound promise of the Internet. This is the wave I started on 10 years ago with blogging. It’s about the democracy of information. Anyone can put information on the web — that’s huge.

UH: Tweet Minister in the UK aggregates the tweets from members of parliament. This is re-wiring society in some ways. But we also have a counter-force – like state control of information.

EW: In some regions, yes, this is bad and hurting the web. But the Internet is a tidal wave that you will not be able to keep out. Like in China, who knows how long those firewalls will hold up – but not forever.

UH: Yes, there are many ways to get through the firewalls already. There’s a lot of pressure on them.

Let’s talk about “betterness.” I booked a trip to his five star resort in an exotic land. When I got there, it was a shack. The manager couldn’t do anything — so I put it on Twitter. Within 15 minutes the booking company called me, and in 20 minutes I got a new hotel. In a half an hour my vacation was fixed.

EW: That’s great. Our hope is that this is the norm, not a fluke. We have a bit of a dichotomy, because there is more everyday you want to search for. We don’t just want to maximize that, we hope to make Twitter more useful to you. We want to decrease time you spend on Twitter, not increase it.

Recently we went through a process to define our operating principles. The number one principle is “be a force for good.” Another principle is “pay attention.”

UH: David Pogue did a campaign against hidden charges from the carriers. It’s the same thing with the hotel operator and me. I know you’re a big fan of Warren Buffet – he also believes in creating real value.

EW: Yes, from a business perspective, Twitter needs to fundamentally be about helping people make better decisions. Or the help something happen that normally wouldn’t. Like the donations to Haiti through text message — we weren’t taking the money, but it spread virally through Twitter. People want to help each other out, we need to reduce the friction.

UH: Is that what you want to do with the new At Platform?

EW: Yes, totally. We’ll see what happens, the obvious stuff is more tweeting, but I think it’s a lowering of the friction as well.

UH: You ask yourself, how would i make Walmart better? Why ask yourself that?

EW: Because as we look at how businesses are using Twitter – we want our tool to help businesses get better.

The world is so often a black box where there is no communication. There’s a lack of dialogue and a lack of transparency. The promise of all these technologies is that this goes away. You close the loop.

UH: Outline for us your big picture goals.

EW: Fostering the open exchange of information. To be a force for good. The ease of exchange of information is important. Help out other people with something as small as a retweet. That’s our ambition.

UH: Google is all about archiving the world’s information. Yours is different — creating new information.

It’s all about advantage though – what’s your advantage.

EW: Our advantage will only come if everyone wins. We only do win-win deals. Because any deal where someone is losing is unsustainable. That’s why we haven’t turned on the revenue yet — there’s a lot of low-hanging fruit, but none of it is sustainable.

Creating an advantage for other people and not giving them a reason to work around you – that’s key.

UH: Is the Internet making a better media industry?

EW: I think there’s a huge shift going on – but it’s an ecosystem where everything is involved. This user-generated content just makes things richer. Blogging and traditional media work together. Twitter compliments traditional media. I was talking last night to some guys from CNN – it’s helped them change what they do. It’s a win-win.

UH: How will the At Platform speak to that?

EW: Hopefully these guys will us it to get the new out there.

UH: What makes you tick?

EW: There are two types of entrepreneurs. What drives me is creating things that didn’t exist before. Your product or service should be at the end of the sentence: “wouldn’t it be awesome if…”

It’s creating new stuff versus extracting from old stuff. There are people who look at money as the goal versus the teams. I create businesses to make new things. It’s a fuel for creating more things in the world. I’ve been lucky to stumble upon things that have helped change the world.

UH: Why focus on these things though?

EW: Largely luck. But maybe it’s what interests me. Twitter was a side project of Odeo – my cofounders came up with it. Blogging was a side project too at one point.

UH: If something is awesome, people will use it.

EW: Yes.

Also, helping others succeed is a sub principle of ours.

UH: Tell us one or two more of them.

EW: Be a force for good, pay attention — make things happen is another one. There’s also building a culture of trust.

UH: What are your big lessons to other entrepreneurs?

EW: Create something you want to exist in the world. Another is focus. Many people are trying to do a lot of things when they should be doing one thing. You may be wrong with whatever you’re trying out, but you’ll try other things.

A lot of the great companies are now coming from outside Silicon Valley. You don’t have to be there.

That’s a wrap.

Brightkite is tricky. Tricky and smart.

While larger than most of their location-based rivals with over 2 million users, they know that in the past year they’ve lost some momentum to the newer check-in services like Foursquare and Gowalla. So they’re trying to do something unique to swing momentum back in their favor.

Today, at the SXSW festival in Austin, Texas, Brightkite is unveiling its new Group Text service. It’s both a feature on the website and a standalone application in the App Store (it should be available shortly). With it, Brightkite is latching onto one of the most popular and fast growing categories in mobile applications: group texting. Unlike regular text messaging, this type of app allows you to message many people all at once (and go back and forth). And better, in a world where cell providers are still managing to rip-off users with their text message bundles or $0.15 rate per-text, group texting is absolutely free.

Services such as textPlus have already made the functionality very popular on the iPhone, and now Brightkite hopes that will translate into converting different types of users over to its core location-based service. The reason is that built-in to the Brightkite Group Text app is the core Brightkite functionality itself. While it’s a bit buried to the left hand side of the menu, you can both check-in at venues, and get check-in updates from other users in the app.

It’s a smart play. As other location services such as MyTown have proven, there’s a market to get users outside of the traditional early-adopter crowd into location by doing something novel (in their case, a straight-up Monopoly-type game). Group texting users seem to be rabid about the software, so why not give them a little location-based bonus to play around with if they desire?

At the same time, this app provides a nice compliment to the Brightkite service itself. With it, users get another social outlet to communicate with, sending messages or pictures, and having them threaded both in the app and online. And yes, it still works with traditional SMS messaging, as Brightkite was lucky enough to be granted a texting shortcode (41414) and it can work with these threaded conversations. For example:

By adding three digits to the end of the code, each person can now have 100 simultaneous threaded text conversations running on their phone.
41414-001 = conversation 1
41414-002 = conversation 2

And thanks to the SMS support, you can contact anyone in your address book, not just those using the app.

The service is now live on Brightkite’s site, and look for it later today in the App Store.

Last night, we wrote about a CauseWorld teaming up with TechCrunch to provide double karma points during the SXSW festival starting today in Austin, Texas. These points, obtained through checking-in at various locations, can be used to donate to charities through big brands that support the app. It’s a great feature, and we hope you’ll use it in Austin. What we didn’t talk too much about is the app itself that enables it, CauseWorld, which just released a new version of its iPhone app in the App Store.

We first covered the app back in December, but now it has been significantly upgraded. One of the core ideas behind the app has always been the intersection of the mobile and physical world (something I’ve thought a lot about as well). A new feature bridges the gap a bit more as you can now scan barcodes on individual items with your iPhone to earn extra karma points. Proctor & Gamble are the ones sponsoring these points on different products they make. It’s a good idea, because even if you choose not to buy the item, it forces you to pick it up and look at it a bit.

This feature points to the bigger idea that CauseWorld parent Shopkick is thinking about when it is ready to launch its flagship product (CauseWorld was born as just a trial site of an idea, but quickly ballooned into an app with over 300,000 downloads). It’s the idea that the cellphone is the only interactive tool you carry in a non interactive setting at all times. So why not use it to make the physical retail space more interactive, Shopkick CEO Cyriac Roeding reasons.

Another huge addition to the CauseWorld app is a social layer. Previously, the app was all about what you did. But now you can hook it up to Facebook (which will earn you bonus karma points) and share the progress and donations you’re making with your friends. On top of this there are new features such as gifting which will help the app virally spread through social networks.

This social layer also allows for a leaderboard to be created showing which of your friend have donated the most karma points. Sometimes social pressure is the best way to get people motivated.

Again, CauseWorld stems from trying out an idea to see what would work with the larger Shopkick plan when that eventually launches. But the response to it has shown Roeding enough that he believes ”the next big thing after the check-in is the check-out.” Given the big brands they’re signing up to support CauseWorld, he just might be right.

You can find the new CauseWorld 1.5 in the App Store here. It’s a free download.

We’ve talked a lot this week about the so-called “Location War” brewing at the SXSW festival in Austin, Texas starting tomorrow. That war will happen, but actually, there are likely to be a lot of winners because a few of the location-based services should be able to leverage the exposure to gain usage after the conference. Those with real bloodlust should probably be watching another war: AT&T versus everyone in Austin on their network.

AT&T’s struggles to stay up last year are well-documented. CNN recently ran a piece about how AT&T hopes to avoid a similar fate this year. But actually, “struggles” is way too kind of a word. If you were at SXSW last year and happened to be on AT&T’s network — like, say, if you had an iPhone, like many festival-goers did — it was an absolute nightmare. You couldn’t make a call. You couldn’t send a text. Data? Ha. At a few points early on I seriously wondered if I had forgotten to pay my bill and AT&T had simply shut my phone off — except that it was happening to everyone.

AT&T has a funny word for the failure, they like to say “unprecedented.” As in, the usage of its network was at level previously unseen as a strong percentage of the over 10,000 festival goers (just the interactive part) were using iPhones. Well guess what? Word is that is year, there will be some 15,000 people there for the interactive part. As Samual L. Jackson’s character, Mr. Arnold, says in Jurassic Park, “Hold on to your butts.”

I’m leaving for Austin tomorrow and I’m terrified of what the AT&T situation will be when I get there. So much so, that I have a back-up plan (which Sprint sent me just in time to test out during SXSW after reading some of my rants against AT&T). With attendance up as much as 50% from the previous year, the number of iPhones in use is sure to be through the roof as well. Did I mention that just about every location-based service known to man is launching an app at the event and hoping every single one of those 15,000 people use it all the time? And based on the early signs, they intend to.

You’ll remember that after Mr. Arnold says the above line in the movie, he’s savagely ripped limb from limb by a velociraptor.

But there may be hope for AT&T. They’re clearly well aware of the failure last year, and did try to solve the issue to minimal effect towards the end of the conference. I asked a company representative what they’re planning to do this year, and they have a plan of attack.

Much of what they sent me is fairly technical, but basically, they now have a system around the Austin Convention Center (where SXSW takes place) that’s the equivalent of 8 cell sites, with 50 antenna nodes to cover the whole venue. Also, they’ve greatly expanded network capacity, moving from one radio network carrier to three, boosting the spectrum available for phones to use. They also say they’ve expanded the capacity of the so-called “high quality” 850 MHz spectrum, which works better indoors because those signals can go through walls more easily. They also have the new HSPA 7.2 software installed at all of the 3G cell towers now. But don’t be confused: that doesn’t mean their network has been upgraded to 7.2 Mbit/s speeds (sadly, at the peak, it’s still half that in almost all of the country), it just means that the upgraded software is in place and should be more reliable and efficient.

But there’s more. AT&T has brought in two Cells on Wheels (the so-called COWS that they brought in to help last year), and also a third rooftop temporary cell site. Each of these are equipped with both 3G and WiFi networks to help alleviate overall network strain. AT&T says these three cells are placed in optimal positions around the city of Austin where they expect the most strain.

All of that sounds great, but I’m still terrified. Why? Because I live in San Francisco. AT&T has known for months that the network is awful here, and while there have been baby steps taken to improve it in some areas, more often than not, it’s still awful. Take tonight, for example. So if AT&T knows it’s bad here, but still can’t seem to fix it, why should I believe Austin will be any different? I don’t. I’ll just have to hope I’m wrong.

Or I’ll have to kick back, relax, and take joy in the bloodbath as iPhones are magically turned into glistening bricks being hurled in anger left and right. As I boot up the Sprint Hotspot, of course.

Back in November of last year, the location-based social event service Hot Potato launched at our Realtime CrunchUp. Today, they’ve taken what was a solid service, and made it a lot better with a number of upgrades.

First and foremost, there is a new iPhone application that just went live in the App Store. With a completely revamped user interface, the app makes it easier than ever to find and participate in events. Perhaps more importantly, it makes it really easy to create new events — and notably, the service has the nicest third-party Foursquare integration I’ve ever seen. When you click on the button to create an event, you can still manually enter a location, but if you happen to be around the venue, you can simply pick it from Foursquare’s list of venues with the click of a button. This drastically simplifies the event creation process since the venue metadata is already there.

This new app will be crucial for the SXSW festival in Austin, Texas, which starts tomorrow. If you’ve been reading TechCrunch over the past week, you’ve undoubtedly seen that just about every location-based service has an app they’re unveiling. And another service based around planning events, Plancast, just launched their app this evening. But Hot Potato offers the best of both worlds as it allows you to both plan future events, and interact with ones currently taking place. The new app makes it very easy to chat about the event, and upload photos and videos.

And they’ve cleaned up the stream of information around these events. There is now a filter to show everyone commenting, or just your friends. There are also now number indicators to show unread items. And the check-in process has been simplified thanks to big green buttons that make it obvious.

Also new for SXSW is Twitter integration. On a case-by-case basis, Hot Potato will be pulling in tweets about certain events at SXSW, using a filter to make sure only relevant ones show up. You’ll be able to do things such as filter those tweets to show only those by people you actually follow, which will make them potentially much more meaningful to you. You can also reply to tweets thanks to integration of Twitter’s API. And you can share tweets from within the app that will show up as retweets on Twitter.

Another new features is Calendars — something which each Hot Potato user now has. Obviously, you can add the events you wish to be a part of to your calendar, but people you are friends with on the service can also add you to other events as well. The app also now features Push Notifications now (on top of revamped email notifications).

On top of the new app, Hot Potato has rolled out a completely revamped website with just about all of the same functionality of the new app (as well as the new look and feel). And at the highest level, Hot Potato finally has its own social graph, which can pull in friends from the usual suspects: Facebook, Twitter, your address book, etc.

And here’s something that should really help Hot Potato this week: each time someone checks-in to a SXSW event with Foursquare, that service will recommend they also join the event on Hot Potato. Clicking on the accompanying link provided in the Foursquare app with open the Hot Potato app and let them join the event with a click (if they have an account). As you might expect, you can also check-in to a venue on Foursquare within Hot Potato. With Foursquare likely to be one of the key apps used by conference goers, this cross promotion is simply huge.

On top of all of this, the service now has its own full API, so others can use and interact with their data.

Simply put, all these updates are full of win, and make a good app even better. And remarkably, they’ve managed to cram in all these new features while at the same time simplifying the overall experience.

Fine the new iPhone app here in the App Store. It’s a free download.

Apple has set the standard that once every year they will release a new version of the iPhone. It stands to reason that this year will be no different, with a new model likely coming sometime this summer. But arguably just as important as Apple’s hardware refresh is the accompanying software refresh that comes with it as well. And that’s why it shouldn’t be surprising at all that whispers of iPhone OS 4.0 are starting to grow. But this year, the timeline appears a bit off.

As AppleInsider reported today, iPhone OS 4.0 is likely to deliver multitasking support. If true, that will make it perhaps the most important OS upgrade for the platform yet. However, in reporting the news, AppleInsider also notes that the software, “remains under development and reportedly has a quite ‘way to go’ before it’s ready for prime time.” Looking back at the iPhone OS SDK history you’ll notice a constant: Apple has released the beta builds in March the past two years. We’re already well into March this year, and so far, no word about Apple being close to doing the same.

In fact, last year, Apple held its iPhone OS 3.0 preview event (where it first made a beta available) on March 17. I remember this well because I was unable to attend as I was at the SXSW festival in Austin, Texas. I also remember when Apple sent out the invites to that event, March 12, because I wrote up the report about it on my way to the airport to leave for Austin. But the difference last year is that there were whispers leading up to that announcement that there would be some kind of event in March for the iPhone OS. This year, so far, nothing.

Now, it’s possible that some of the speculation about the new iPhone OS release has been muted because of the recent iPad unveiling, and it’s upcoming launch on April 3. But that very launch also adds fuel to the fire that we won’t be seeing an iPhone 4.0 OS anytime soon. After all, Apple is currently in the process of rolling out the beta builds of iPhone OS 3.2 (currently on beta 4), which is the OS the iPad will apparently ship with.

The launch of the SDK is important because it gives developers time to get their apps ready for any big changes coming. And multitasking seems like it would be a pretty huge change, though it’s not entirely clear if most of the work would be done through the OS itself to optimize how app resources are managed, rather than apps having to do that themselves to be deemed “multitasking ready.” Hell, it’s not even clear if any iPhone beyond the inevitable new one will be allowed to let third-party apps run at the same time as the new hardware will undoubtedly have a faster processor (possibly the A4 found in the iPad), more RAM, and maybe even a better battery — all of which will be crucial to multitasking.

I’ve spoken with a few developers and none have yet seen any part of the iPhone 4.0 OS. A few have gotten word from the company that it is indeed coming, and that big changes are in store (which had led me to speculate about background running in the past) but have no idea when that will be. Apple, meanwhile, has been thinking about how best to let third-party applications run in the background on the iPhone for about a year now.

It seems unlikely that Apple would launch a new iPhone OS without giving developers plenty of time to play around with it. And since there is no word about the 4.0 SDK coming anytime soon, that could well mean a push from the usual June/July timeframe for a new (final build) iPhone OS launch. Might we see new iPhone hardware that launches with OS 3.2? And then iPhone OS 4.0 would be released as a free upgrade closer to the Fall timeframe? It certainly seems possible.

As I’ve made abundantly clear over the past several days, just about every service that has anything to do with location is launching something at the SXSW festival which starts tomorrow in Austin, Texas. Don’t believe me, here’s a small sampling (Foursquare, Gowalla, Loopt, Whrrl, Plancast, Brizzly, Twitter). So, how are you going to wrap your head around all this location data? SimpleGeo has an awesome way.

Vicarious.ly is a real-time location-based stream of information presented in a nice visual way. While the plan is to eventually launch one for many different cities around the U.S. and eventually the world, the first one is based around Austin, for SXSW. To make it, SimpleGeo partnered with BlockChalk, Brightkite, Bump Technologies, Flickr, Fwix, Foursquare, Gowalla, and Twitter to pull all of their location data and place it both in a constantly-updating stream, and put data points on a Google Map at the top of the page. These data points are represented by the logos of the various companies, so it’s easy to follow visually.

Those concerned about the privacy implications of this need not worry, Vicarious.ly doesn’t pull actual user names from the companies mentioned above. Instead, they simply note that “someone” checked-in at a venue. They do, however, give the venue name, which is a hyperlink. So if someone just checked into Stubb’s Bar-B-Q in Austin on Gowalla, you’ll see a link back to the Gowalla page for that venue. Likewise, if someone uploads a geotagged picture to Flickr, you’ll see a thumbnail of the picture in Vicarious.ly’s stream, and clicking on it will take you to that picture’s Flickr page.

It’s fairly amazing to see just how much activity there is even today, the day before the conference starts. Tomorrow and the weekend should be insane. “The amount of real-time, location-based information we’re indexing is staggering.  We wanted a powerful way to showcase that, so we built Vicarious.ly and targeted the launch to coincide with a massive gathering of geeks,” co-founder Matt Galligan says about the project.

You’ll note just how much of the activity are check-ins from either Foursquare or Gowalla. Those two are likely to be the two main competitors in the location war that will take place this weekend. (If you’re surprised not to see tweets in the stream, it’s a bug that SimpleGeo hopes to squash tonight).
