T-Mobile USA is the only major mobile network not offering the Apple iPhone officially on their network.
The company however does offer support to owners of the unlocked and jailbreak iPhone units.
T-Mobile USA has now revealed that they would offer Nano-SIMs to owners of the latest iPhone edition that was announced recently.
Apple iPhone 5 is the first smartphone in the market to use this new SIM standard. Users would have to get this new SIM from their carriers to make it work on their iPhone 5.
@ceciltavares We will be looking at getting them mid October :) ^LS
