Apple Testing iPhone for T-Mobile USA
BGR provides photos of an iPhone prototype that supports T-Mobile USA's 3G service.
Thats right, youre looking at photos of an iPhone prototype with T-Mobile USA 3G bands. The actual internal model is N94, and if you remember, the Verizon model is N92 while the standard GSM variant is N90. We have verified that the phone itself is running a test version of Apples iOS, much like the one we saw in those videos from Vietnam, and it includes internal Apple test apps like Radar and Apples employee directory app.
The T-Mobile US network uses different frequencies than AT&T's, requiring different hardware to support. It's not clear what this will mean given that AT&T is planning to acquire T-Mobile USA, though that transaction will take some time before it goes into effect. In the meanwhile, T-Mobile continues to operate as an independent carrier in the U.S.
