Apple's iPhones were the top three most popular smartphones in the United States for all of 2011, according to comScore's 2012 Mobile Future in Focus whitepaper. NPD reported similar results for the months of October and November, when the iPhone 4S was the most popular smartphone in the country after it was released.
For the full year, the iPhone 4S was the country's third most popular smartphone model, beating every other non iPhone model, even though it was only on sale for the final three months of the year. As they were on sale for the full 12 months, both the iPhone 4 and 3GS outsold the iPhone 4S. In fourth place was a single BlackBerry model, followed by the only Android device on the list: the HTC Evo 4G -- a Sprint exclusive, and the first 4G phone available in the US.
