I gave the phone to woodrow, and he just swapped out the chip for his prepaid plan. If you have a real plan, I was told by Cingular that I just had to bring in the phone and they’d hook it up no problem.
The phones overseas don’t have “Cingular, Verizon, etc.” written on them anywhere. So if someone gave me a hassle about it, i’d just go to a different provider.
