The Apple handsets jumped from 31 percent share to 45 percent in a single year, while Android phones also did well, going from 11 percent to just over 20 percent, an even higher growth rate that put it in third place. The growth came at the expense of rivals, principally Symbian and Windows Phone, though the Blackberry suffered a small drop as well.
