Aging iPhone 4 and 3GS Remain the Best Selling Smartphones in Q3

A new NDP study reveals that the iPhone 4 and 3GS hold the top two positions in U.S. smartphone sales during Q3. The five best selling mobile handsets were as follows:

1. Apple iPhone 4
2. Apple iPhone 3GS

  • The average price for smartphones has fallen four consecutive quarters and is now $135 per device.
  • The share of U.S. mobile handset sales that were smartphones reached 59 percent in Q3, a 13 percent increase quarter-over-quarter.
