According to the NPD Group, a market research firm, Android has usurped Apple for the #2 spot in the US smartphone market. RIM still leads the pack with it’s Blackberrys (-ies?) commanding a 36% market share, with Google’s Android OS now at 28% and Apple’s iPhone at 21%. AT&T, amazingly still the only company to offer the iPhone in the US, is still the leader of the pack with a total 32% of the smartphone market with Verizon trailing closely behind at 30%.

With the release of the iPhone OS 4.0, the next generation iPhone (Potentially called the iPhone HD), and a rumored Verizon offering all coming this summer, one can likely expect the iPhone’s market share to climb back up by fall and potentially retake second place.
