my cingular account has ended today and now i have a sim card for t-mobile. my iphone is on the 2.0.2 firmware and i think it's the 1g or 2g one? i purchased it in september 2007 (not 3g). does anybody know any step by step tutorial to follow to unlock my iphone to work with t-mobile?
also, how can i remove my cingular sim card? i remember the workers at the apple store had a special key to take it out.
and when i unlock my iphone, what plans should i sign up with t-mobile to have the unlimited web and internet?
