Survey: iPhone 5, 4S are world's top two popular smartphones
Apple's dramatic uptick in iPhone sales in the final calendar quarter of 2012 put its two leading iPhone models -- the iPhone 5 and the iPhone 4S -- at the top of the heap as the current most popular smartphone models in the world, according to handset industry monitoring firm Strategy Analytics. Together, the two iPhone models sold over 44.8 million units in Q4, handily surpassing its nearest rival, Samsung's Galaxy S III (which shipped 15.4 million units, a sizeable decline from the prior quarter).
