Android Passes iPhone OS in U.S. Purchases

The Blackberry passed the iPhone by the same basis. Verizon pushes the BOGO to inflate their unit sales of the Blackberry Storm- sales of which have practically ceased since. The Curve is the only thing keeping Blackberries in the running, and that's because they're 2010's Motorola RAZR.

Another thing worth mentioning is that many of Verizon's 'sales' are coming from exchanging Android handsets (not warranty replacements but customer handset exchanges for separate SKU's.)
