According to R.W. Baird analyst William Power, “the HTC One continues to be noted frequently as the third-best-selling device behind the iPhone and S4″ on AT&T, Sprint and T-Mobile. Of course, the HTC One hasn't made its way to Verizon just yet, and Verizon is the largest carrier in the country.
Reports from earlier in the week have put the HTC One sales at around 1.2 million devices per month, which would likely put the handset at a respectable, but fairly distant third place behind the powerhouses from Samsung and Apple. That number is sure to rise when the One comes to Verizon in the next few weeks.
