Bought someone's two month old iphone, threw out SIM from ATT, reset phone....I didn't know!!! Now all it says is emergency calls only. I paid to unlock it at jailbreak my iphone.com but I can't even start because when i try to use itunes, it wants the SIM. I have a SIM (from the Bahamas) but not the ATT original. Furthermore, I don't even know what firmware my 3G is using because the only way i know how to check is blocked by emergency calls! Soooo confused and need help!
