As it has said many times before, T-Mobile is eagerly awaiting the arrival of the iPhone on its network. The carrier has been largely unable to attract unlocked iPhone owners due to the fact that frequency incompatibilities make it impossible to use 3G data speeds on T-Mobile’s 1700 MHz AWS band. T-Mobile started transitioning part of its spectrum over to the iPhone-friendly 1900 MHz band last year, and scattered reports have said that a small number of iPhone users can now use 3G speeds in certain areas of the United States.
Not only is T-Mobile saying that its 3G network will be ready for the iPhone by Q4 of this year, but it also plans to offer HSPA+ 4G speeds on an iPhone-friendly frequency.
