Hi guys I have an iPhone 3gs that was on 4.3 and had the baseband 6.15.00. I purchased this from eBay after the guy claimed that the phone was unlocked. Anyway, after attempting to upgrade/restore the iPhone I now run into the 1015 error code. I think the guy must have had some custom firmware installed. I am hoping I can salvage this - I am not bothered about it being unlocked - I just want it back like it was originally. Can anyone help me? Is there a guide to getting around this? I have jailbroken iPhones before but I am far from technical when it comes to these things. I really would appreciate your help!
