The Android platform has been growing at an unprecedented pace and has already been the number one smartphone platform in the world since a few months. It had also overtaken iOS in the US and going by the latest data from January 2011, it has now edged out Blackberry to become the number one smartphone OS in the United States as well.

According to data from Comscore, Android now has a 31.2% share of the US smartphone market. RIM follows in the second place with 30.4% and Apple takes the third spot with 24.7% share. This data doesn’t cover the effects of the iPhone 4 now being available on Verizon, but I doubt that will change the overall picture much. Android is still growing at an insanely fast pace, and at the expense of Microsoft, Palm and Symbian. Despite the launch of Windows Phone 7, Microsoft has actually lost share.

Nielsen’s data shows a similar trend – Android has a 29% share which is way ahead of iOS and Blackberry both at 29%. With more impressive Android devices coming soon, Android will soon dominate the market by a huge margin. Even Apple’s marketshare has been cemented by its loyal fans. With the support from Nokia, Microsoft’s marketshare is expected to rise at least a bit in the coming year. The smartphone wars are going to be very interesting.
