iPhone is the most popular US smartphone while the Android army’s march has propelled that multiplicity of devices to become the most popular OS, Canalsys reports today. The analysts note massive growth in the sector – the worldwide smartphone market grew by 95 percent over the year ago quarter. Nokia stays ahead of the pack with 33 percent while Apple grabbed 17 percent worldwide, putting it above RIM. Canalsys’ figures closely match those revealed last week by Strategy Analytics and IDC. “Devices running the Android platform that proved the greatest driver of growth in the worldwide market, up 1,309% year-on-year from 1.4 million in Q3 2009 to more than 20.0 million units in Q3 2010, forming a quarter of the market share. ‘With Samsung, HTC, Motorola and Sony Ericsson all delivering large numbers of Android devices, and with focused efforts from many other vendors, such as LG, Huawei and Acer, yielding promising volumes, the platform continues to gather momentum in markets around the world,’ said Canalys Senior Analyst Pete Cunningham”
