Neither HTC nor any U.S. carriers have shed much light on their One launch plans yet, but a new AT&T promotional video for the device has revealed a couple of interesting tidbits of information about the big blue carrier's One variant. The promo video, which was posted to AT&T's official YouTube account yesterday, talks up HTC One-specific features like BlinkFeed and its UltraPixel camera. As discovered by Droid-Life, the clip also mentions twice (once at 0:27, again at 4:40) that AT&T will offer both the 32GB and 64GB versions of the HTC One, with the 64GB size being exclusive to AT&T.
In addition to offering two built-in storage options, AT&T will apparently offer both the silver and black versions of the HTC One, which it refers to as "glacier silver" and "stealth black." And as with most other smartphones on major U.S. carriers, the One will be sporting some AT&T branding once it hits store shelves. Below you can see an image showing a small AT&T globe logo at the bottom of the One's rear, which is similar to the branding we saw on AT&T's flavor of the HTC Windows Phone 8X.
HTC has said that the One will be available on AT&T, Sprint and T-Mobile here in the U.S., but if this new promo video is accurate, it looks like customers on Sprint and T-Mo will only be able to pick up the 32GB version of the One. It's been rumored that a Verizon variant of the HTC One is also on the way, but so far there's been no official announcement concerning that model. Obviously it'll be kind of a bummer if AT&T is the only U.S. carrier to offer a 64GB version of the HTC One, especially since the One doesn't have a microSD slot for additional storage. The upside, I suppose, is that at least the smallest One has 32GB of built-in storage and not 8GB or 16GB like some other recent smartphones with no expandable storage.
HTC has said that the One is slated to begin arriving in North America before the end of April. There haven't been any launch details revealed by AT&T, Sprint or T-Mobile yet, but we should be hearing something soon if the One ends up hitting the U.S. before next month wraps up. Until we hear more, we've got AT&T's promo video for the One embedded below for your viewing pleasure.
