Walter Piecyk, BTIG Research analyst claims that, according to a study his firm performed, the HTC Thunderbolt is actually outselling the iPhone in 28% of Verizon stores. Piecyk and his team called 150 Verizon Wireless stores in 22 major U.S. cities. They asked each store which device was selling better. According to his report, 61% indicated they were selling at about the same pace, 11% said the iPhone was selling faster, and 28% confirmed that the HTC Thunderbolt was selling faster. Obviously, this isn't the most highly controlled nor scientific method for testing, so it should be taken with a grain of salt. However, it is still telling that it is very likely the Thunderbolt had a very strong launch.
