Long story short. My g/f got me a cell for my b-day(at&t blackberry 7280) i went to get it activated but i can't. First i signed with t-mobile and they said there sim card would work(WRONG) and the said they would unblock it if i stayed with them and waited 6months. So i went to an at&t store and they said they couldn't give me a plan to work on my phone unless i had an at&t simcard. Sence i don't i guess im SOL. The chick at the store told me she would unlock it for 100$ but im don't want to shell out that kind of money for a phone i got for free. So does any one know how to "Unlock" a blackberry?
