The latest comScore data, based on consumer surveys (n=30,000), show that the Android surge continues. While the Verizon iPhone was reportedly the most popular individual handset in February, the Android collective -- supported by the top three OEMs -- has now overtaken RIM too. ComScore says that 29% of US mobile subscribers have smartphones -- a number that is now probably low -- vs. Nielsen's 31% estimate. 

In part benefiting from Android growth (and vice versa) Saumsung was the most popular handset OEM in the US. While Android gained 7% during the three-month period former smartphone leader RIM was off almost 5%.

Now compare the same charts from a year ago (February, 2010): 

Apple's iOS has remained constant, as a percentage of the overall market, according to comScore's figures. Android's success vs. the iPhone is based in part on its wide availability from a range of characters and price points. The iPhone remains available from just two US carriers and is restricted to contract customers.
