BlackBerry Curve overtakes iPhone to become top selling U.S. smartphone in NPD rankings

The top five models in the smartphone niche include all BlackBerry Curve models (83XX) leading the way, followed by the Apple iPhone 3G. Third place goes to the touchscreen BlackBerry Storm followed by the BlackBerry Pearl (all models except for flip) and T-Mobile's G1.
With some strong new smartphone models coming to the States, including some BlackBerry models and the second Android device, the standings could be in for some changes in the next two to three quarters.
