Watch out RIM and Apple, the little green guy is knocking on your front door to claim the title of most sold smartphone operating system in US 2nd quarter of 2010. NPD is reporting that Android had 33% of US device sales followed by RIM with 28% and Apple with 22%. NPD is crediting HTC and Motorola with the huge surge in Android device sales and we certainly don’t disagree. It looks like Android definitely has the momentum to hold the top spot in the US smartphone market, and with RIM’s slightly disappointing BlackBerry Torch 9800 launch yesterday it doesn’t look lik RIM will be taking back their title anytime soon.
