I have been a T-Mobile USA customer for over 10 years and have five phones on a family plan with them, but my family can only use unlocked iPhones at slow data speeds. Our friends at TmoNews just reported the Tweet sent out by Duetsche Telekom that will please many T-Mobile USA customers and it looks like they may finally be getting the iPhone. If this happens, then I may be able to eliminate one of the carriers in my mobile arsenal.
T-Mobile USA has entered into an agreement with Apple to bring products to market together next year.
Deutsche Telekom is holding their investor day event and statements are just now coming out about this agreement so we don't yet have many details on any specifics. T-Mobile has been rolling out support for the 1900 MHz frequency, which allows unlocked AT&T devices to work on T-Mobile's network at 3G data speeds. We are not yet sure if Apple will be selling the current unlocked iPhone 5, something they just recently started selling online, while T-Mobile promotes this band rollout or if Apple will actually make an iPhone that works by design across the T-Mobile network. T-Mobile will soon be launching LTE in the US as well so it could be a future LTE announcement too. All we know at this time is that they entered an agreement for a 2013 product launch.
UPDATE: TmoNews added more details about the agreement.
