No wonder Apple is suing HTC for patent infringement over its Android phones. In the three months between October and January, Android’s overall share of smartphone subscribers in the U.S. rose 4.3 points to 7.1 percent, according to mobile market share data released by comScore. Android showed the biggest single gain of any of the top five smartphone platforms. Apple’s share was virtually flat at 25.2 percent (up 0.3 percent), while RIM’s Blackberries saw a 1.7 percent gain to 43 percent.

Our full review of the Motorola Backflip should be up in a few days, but a few words of wisdom in the mean time: Don’t buy it. Between its crazy form-factor and the hidden trackpad tucked on the back of the display, everything we took as merits at face value have devolved into novelties.
Worst of all, it seems AT&T has taken a page from their time with the iPhone that no one wanted them to take. Like the iPhone — but unlike any other Android handset we’ve seen — the Motorola Backflip can’t install applications from any sources beyond the official, on-handset application store.

It’s hardly a secret that all of the major location-based players are planning big updates to their services to coincide with the SXSW festival starting next week in Austin, Texas. One of them peeked out a bit early: Foursquare.
Earlier today, the latest version of Foursquare, 1.6, went live in the App Store for a brief period of time. I’ve been using the build for a couple of days, and while the functionality isn’t all that different from the previous versions, the look-and-feel has been completely revamped.

Research reports forecasting future market sizes should always be taken with a grain of salt, but it occasionally helps to see the estimates of research organizations in order to gain some perspective on the current and upcoming trends for those markets.
With that in mind, let’s take a look at what research2guidance has to say about the worldwide smartphone application market, which it estimates will grow from $1.94 billion in 2009 to $15.65 billion by 2013.

Adobe this morning announced that third-party developers now have access to the Photoshop.com Mobile for Android 1.1 editor, allowing them to make it a part of their applications.
The news comes four months after the company released Photoshop.com Mobile for Android, enabling users to easily edit and share their photos. That app got an upgrade, too.
Amusingly, Adobe also takes a bit of a swing at Apple for not being able to provide such tools to iPhone app developers.

Mobile data is on fire. Despite a few false starts, we are now in the midst of a transformative “Open Mobile 3rd Wave” (remember WAP, and J2ME?). We are just in the early swell of the wave; the iPhone itself is not even three years old, and thanks to continued improvements we’re now seeing in smart phones, mobile OS platforms and 3G/4G networks, the raw ingredients are just getting better every month. Per the views of many mobile denizens and thought-leaders such as well-known internet analyst Mary Meeker of Morgan Stanley, I certainly believe there will emerge new industry-transforming Facebooks, Googles, and Yahoos in this mobile wave.
However, a key topic discussed by us mobile geeks and startups is the challenge of mobile platform fragmentation. There is an alphabet soup of protocols, standards, and regional differences by-country which can be daunting for any entrepreneur.

In December 2008, Microsoft surprised a lot of people by releasing an iPhone app — Seadragon Mobile. A month later, they ensured the move wasn’t taken as a joke or gimmick by launching another app, Tag, into Apple’s App Store. Now, they have a few, including an app for Bing. And starting today, they’re doing the same for Android.
Tag for Android is the first Microsoft-made app launched on the mobile platform. This is notable, of course, because Android is the mobile platform by Microsoft’s chief rival: Google. Still, as we saw with the iPhone, Microsoft has no problems getting its technology out there, even if it means using rival platforms. Aside from Android and iPhone, Tag also currently works on Windows Mobile, J2ME, Blackberry and Symbian S60 phones.
As you’ve undoubtedly heard by now, Apple has filed a lawsuit against device-maker HTC over 20 patents they control. As you might imagine, Google has something to say about it too.
“We are not a party to this lawsuit. However, we stand behind our Android operating system and the partners who have helped us to develop it,” a Google spokesperson emailed us.
Google has just sent out an Email to select Android developers informing them that they are eligible to receive either a Verizon Droid or a Nexus One, as part of its ‘Device Seeding Program’. The criteria for getting one of the phones is to have an application with 3.5 stars or higher and more than 5,000 downloads, which sounds like it could include quite a few developers.
In an odd move, Google isn’t actually allowing the developers to pick which device they’re receiving — if you’re in the US, you’ll get a Droid or Nexus One, at random. If you’re in Canada, the EU, Norway, Lichtenstein, Switzerland, Hong Kong, Taiwan, or Singapore, you get a Nexus One. If you’re not in any of those, you don’t get a phone at all (Google explains that the phones aren’t certified in other countries).

Earlier today, Apple issued a press release stating that it has filed suit against cell phone manufacturer HTC for patent infringement. No mention of Android or Google was in the press release. But the actual legal complaints, which we’ve obtained and embedded below, make no bones about it. As expected, this lawsuit is about Android. HTC, of course, is one of the largest manufacturers of Android handsets.
The complaint filed in U.S. District Court in Delaware targets: “certain mobile communication devices including cellular phones and smart phones, including at least phones incorporating the Android Operating System (collectively, “the Accused Products”).” And the complaint filed with the U.S. International Trade Commission specifically calls out the various HTC Android phones (including the Nexus One, Magic/myTouch 3G, Dream/G1, Hero, and Droid Eris) as the main offending products. By going after the biggest Android manufacturer, Apple is putting all Android cell phone makers—and by extension Google— on notice. Is there any doubt now why Google CEO Eric Schmidt had to resign from Apple’s board last year? The battle lines are now drawn.
The patents that it says are being infringed include:
