Engadget Mobile is reporting that the HTC One, the uber-drool worthy device that it is, will be debuting next month as an AT&T exclusive device. If in fact this is the case, you can rest assured that Samsung just sold another 15 million Galaxy S IV handsets to those impatient Sprint and T-Mobile users. It is one of those facts that ends up escaping the sales charts later. When HTC looks back on this quarter’s sales figures, it only needs to look at this as the reason they lost another round to Samsung. Hoepfully, this is one of those horrible rumors that will not come to pass, but if it does, HTC will have some major issues soon.
