iPhone 2G Accidentaly upgraded
I have my friends iPhone 2G which has been recently upgraded accidently. I think he was on firmware 1.1.3. I dont know the unlock mechanism use on his iPhone originally.
I am trying to look up for the iphone version using the key codes but it doesnt show up the page where the firmware version and other information is available.
Since he is not a techie he doesnt even know which version of firmware he has used to upgrade from iPhone.
Also, I have a windows PC and wanted to know what are my options to unlock and jailbreak the phone ?
