U.S. iPhone 6s Release All but Confirmed
T-Mobile is offering a solid iPhone 6 deal that lets its customers purchase the iPhone 6 or iPhone 6 Plus right now and then upgrade to the new models before the end of the year. In other words, a T-Mobile iPhone 6s release is already confirmed.
The carrier's iPhone 6 deal lasts until September 8th, a day before the rumored launch date, and it's very clear that the Uncarrier will be playing host to the new iPhone. John Legere and Co. wouldn't have made a promise that early if they didn't plan on keeping it.
AT&T, Sprint, U.S. Cellular, Verizon, and others should also be a part of the iPhone 6s release date though we might not see them confirm until September.
