I've had an iphone for a year and i've broke 4 and my current one is broke again... So buddy gave me his curve 8320 set up for tmobile. i unlocked it to work on at&t and i can make calls and txt. But it still says Tmobile when it boots and loads stuff and has all the tmobile apps on it. Plus some of the apps for tmobile wont work of course. How can I completely wipe all this software from tmobile off of it and reinstall at&t's software?? and where would I get this at&t software from?
