Hi all, I've fished out my old 3GS iphone (without sim) that I'd like to unlock and give to my dad to replace his Nokia 3310 I've reset the phone to factory defaults, via the phone itself. However, in order to unlock it, how do I know which iOS version it's running? I believe when I last used the phone, it was updated to iOS6 probably, but I'm unsure if the factory reset will have set it back to the original OS or not. Will it now be iOS3? Is there anything else I'll need to know about my phone in order to unlock it? If useful, the phone is Model: A1303 Many thanks - merry christmas!
