Checks performed by Canaccord Genuity analysts T. Michael Walkley, Charles John and Matthew D. Ramsay show that Apple’s devices maintained their dominance in the U.S. market in June. The firm contacted carrier retail stores across the country to determine which smartphones were the most popular last month. At AT&T stores, Apple’s iPhone 4, iPhone 3GS and the Samsung Infuse 4G were the most popular devices, as they were in May. Apple’s iPhone 4 was also the best-selling smartphone at Verizon Wireless stores again in June, followed by the Samsung DROID Charge and the HTC Thunderbolt. The brand new HTC EVO 3D topped EVO 4G and Epic 4G sales at Sprint last month, and the HTC Sensation 4G, Samsung Vibrant 4G and myTouch 4G were top-3 at T-Mobile. Canaccord found that iOS and Android showed growth in June while BlackBerry sales slid at all four carriers, and Motorola’s North American sales continued to slow as well. A chart showing Canaccord’s findings over the last six months can be seen below.
