So we know that Sony’s Xperia Z flagship Android smartphone will be coming to the US, and it was earlier last month that we saw the handset pass through the FCC with T-Mobile’s radios on board. Well in case you were still a bit skeptical, support documents for the Sony Xperia Z have popped up on T-Mobile’s website, hopefully putting an end to any doubts you might have had of the phone arriving stateside once and for all. It is still unclear as to when the handset will be announced, or why there is a holdup considering that the phone has already been confirmed and sighted as the FCC, but we guess with all this “proof”, an announcement of the handset is imminent, so be sure to check back with us in the near future for more updates. Anyone planning on picking up the handset for themselves upon its release?
