Getting Locked SIM Message?
I went out and bought an iphone from Craigslist, and its running 3.1.3 and 5.12.01 . I have AT&T, and he said my sim card would work after connecting it to itunes. I did this and nothing works, when I put my SIM card into the phone and turn it on a message pops up that says "Locked SIM" and gives me the option to unlock or cancel. It gave me 3 tries, I used the first two guessing the defaults of 0-0-0-0 and 1-1-1-1 and now I don't know what to do. How can I get the code for my SIM? I called AT&T and they gave me the PUK code and that didnt work, even though I think that code is for once I used up my third try to unlock the SIM. Any advice on what I should do??
