Will TMobile USA ever be Apple iPhone's carrier?

TMobile needs to step up their game in America a lot if that is ever going to happen.

I doubt it…Apple has no real reason to start making them for t-Mobile. They are smaller compared with ATT and Verizon.

I have T-Mobile and wouldn’t give them up at all. :)
An unlocked iPhone works fine on the network and you’ll be paying a LOT less for the data.

Last I saw AT&T had secured exclusivity for the iPhone thru 2010

Had TMo for many years. Unless you can find a better plan, or a phone (like the iPhone) that you are willing to pay more for, don’t leave them. I was always happy with their service, their price and their response to any problems. Anytime I had to call them I got a live person within 4–5 rings.

Now I use Sprint, because they offered me a killer plan ($30 for 500 min, free data and SMS). If Sprint ever cancels my plan, I will most likely go back to TMo!
