Hi guys, I'm not the most tech savvy guy out there, althoough I have spent hours looking for a solution to this problem online before discovering your forum. In short, my Galaxy s3 went for a swim the other day. It's goosed, but that's not the problem! My wife's sister gave me her old Iphone 3G (A1241) to use in the interim. She was on the O2 network (as am I), but when I put my SIM in the phone it says insert a valid SIM with no PIN lock to activate iphone. It's at the can only make emergeny calls stage. Can anyone advise me on how I can use this phone? Or point me in the direction of how to unlock/jailbreak it? If that's whats required. I even called a phone unlocking store, but she told me it would be stuck on an old version and I wouldn't be able to use many apps etc... I'm assuming she meant I would be stuck on some old firmware... Any help/advice gratefully received! Many thanks in advance. Regards, Joe.
