Also for anybody thinking about upgrading there phone, I am using the MyTouch4G and its freaking amazing. If you like stock espresso then you might not even root the phone its flipping amazing. But once rooted the MyTouch4G gets even better with great Roms by Gr8gorilla, Evil D and of course Cyanogen. The root process is very easy. You can also OC the 4G to a very stable 1.8ghz. The MyTouch4G is the best Tmobile phone available as of right now. lol
Sounds like a good phone, hope AT&T doesn't screw it up for you.
