In spite of seeming pressure, the iPhone 4 is still the top-selling smartphone at AT&T and Verizon by a wide margin, Canaccord Genuity
said in a new research note. Checks showed that the Apple phone was still "by far" the most popular in May and June, even after phones like the Samsung Infuse 4G
and Sony Ericsson Xperia Play
arrived on shelves. While sales of Motorola's Droid X2 were "steady," Motorla's Atrix 4G at AT&T and Xoom tablet at Verizon were both "disappointing," research lead T. Michael Walkley and other analysts said.
