iPhone 4 and 3GS Rank as Best-Selling U.S. Smartphones

Research firm NPD has recently announced results of its Mobile Phone Track report for the second quarter of 2011. Android is still leading the U.S. smartphone with 52% of the market; Apple's iPhone has 29% while BlackBerry devices only 11% of the market. But the 14-month-old iPhone 4 is continuing to lead the market in sales, and the 8 GB 26-month-old iPhone 3GS takes the second place, perhaps, because its that price now dropped to $49.

Here are the top five best-selling phones during Q2, via NPD’s Mobile Phone Track service:

1. Apple iPhone 4
2. Apple iPhone 3GS
3. HTC EVO 4G
