Trade in a 16GB iPhone 6, and you can get an iPhone 6S for $1 a month or an iPhone 6s Plus for $5 a month.
iPhone and iOS news
Sprint and T-Mobile each announce what look like incredibly cheap pricing for the new iPhone 6S and 6S Plus. What's the catch?
This marks the lowest monthly rate for an iPhone in an increasingly competitive environment. The carrier also confirmed it would sell the Apple Watch on Friday.
The carrier's outspoken CEO John Legere touted T-Mobile's iPhone 6S preorders in a Tuesday tweet.
The carrier is shaking things up again with a program that lets customers using the latest smartphones easily cancel their T-Mobile service if they can't get a signal wherever they are.
The company also adds Apple Music to its program that lets you stream music without counting against your data plan.
That's the only way they'll solve real problems, says Glenn Lurie, speaking at the Code Mobile conference. He also notes that the iPhone 6S has sold well.
Reports of crashes and reboots have popped up on various online forums, seemingly specific to T-Mobile iPhones. But so far there's no official word on the cause of the problem.
Some new software tucked into iOS 9 beta will let T-iPhones play with Apple's Continuity feature over T-Mobile's cellular network, not just over Wi-Fi.
Using the regular phone interface, T-Mobile subscribers can make and receive video calls from Samsung's new Galaxy S6 Edge+ and Galaxy Note 5.
