Sony Xperia T arriving on AT&T: press shots with carrier's logo surface
Interestingly, the AT&T-inscripted Xperia T has a slightly different design than the international version. The back is divided clearly into three sections, while the international version of the phone features a smooth, uninterrupted back cover.
Could this be because the AT&T-bound Sony Xperia T has to integrate LTE radios? We don’t know, but that’s one likely reason. There are no details like pricing or a release date, nor an official confirmation by the carrier, but we guess we’d be hearing more about this soon, so stay tuned.
