Research firm Kantar Worldpanel has found that the huge demand for Appleís iPhones in Q4, driven by the arrival of the Siri-toting iPhone 4S, has catapulted Apple past the combined sales of all Google Android-powered smartphones over the same period. According to the data, Appleís share of the critical US market doubled year-over-year for the quarter just passed to 44.9 percent. This just beat out Google Android smartphones, which dropped from a 50 percent share to 44.8 percent.
