T-mobile coming out with iPhone in 2013? - 1

When approximately do you think T-mobile will start carrying the iPhone in 2013? Towards the end of the year, mid-year, etc.

Beginning of the year

T - Mobile Already carries iPhones. You have to have it unlocked but they already carry them. My mom had the iPhone 4 and is on T Mobile service provider

If I remember correctly, March 2013, but I read that awhile ago, so it could have changed
