i was online and searching for expert engineer who can unlock my 3g iphone.
Check the base-band version first. If it's 02.30 and not 02.28, then u r out of luck. Well, if your boot-loader is 5.8, you are in luck, but I doubt it is. For more info, use google. Or if you are afraid of "frying" your iPhone and you are in Lagos, send an email to email@example.com. No, I am not an expert engineer, but I can help you.
