All the HTC One hubbub in New York and London is for naught if you can't get your hands on the phone. So AT&T, T-Mobile, and Sprint customers in the United States will be glad to hear that their carriers are already confirmed to get HTC's shiny new flagship. Both AT&T and T-Mobile have reached out to us directly with confirmation, and Sprint is listed in HTC's official press release along with regional carrier Cincinnati Bell. Sprint had a sign-up page available briefly, but it seems to have disappeared. Sorry, Verizon users, you'll just have to make do with the DROID DNA for the time being.
