Hi guys I have been asked to help a friend, to fix his iphone 3G. The iPhone is bought in Thailand, and it worked fine, up untill the point where he tried to sync it with itunes. Afterwards, it has refused to gain any signal whatsoever. I have checked the serial number on Apples website, to ensure it isn't a mock up, however, on the lock screen, under the clock, the language is some chinese stuff, while the rest of the phone is danish. Do you guys think it needs to be unlocked? jailbroken, synced again or what?
