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.

(View all)And looking at "carrier acquisitions" here, Rogers acquired Fido ages ago, yet even though the networks worked on the same GSM bands, they still haven't merged. An AT&T purchase of T-mobile would probably take years for a merge to even occur, and a few technology changes. AT&T isn't going to retrofit T-mobile's network and change their frequencies, requiring all the existing customer base to change phones.
So even in a US Centric view, it makes a lot of sense. Basically, don't let an AT&T acquisition of T-mobile trick you into thinking this is a false rumor.
