The sustained effect of the iPhone 4S launch has kept the iPhone growing at the same pace as Android in the US. Google's platform grew a collective 2.5 points over the fall to 47.3 percent, but Apple nearly matched it with a 2.2 percent hike to 29.6 percent. As with much of the past year, the two were only really drawing from other platforms, with the BlackBerry down nearly three points to 16 percent.
