I got this phone from a friend of mine back in September, and I used my (temporary) AT&T card when I was in Hawaii (exchange student), so I had to return the chip to the owner. Now that I don't have an AT&T SmartChip or SIM card, I can't use it, so I wish to unlock it. How can I do so?
Note: I have no idea whether the previous owner had a plan or it's pre-paid :S
