New to the iPhone (hacking) world but I got given a hacked iPhone for christmas and was wanting to update it to a newer version. I am more than a little overwhelmed with it all and have been reading through various guides and information, mainly hackthatphone. However I am a little confused at my starting point. I have a hacked iPhone that is currently on 1.0.2 and working with an 02 UK simcard it has firware version 04.02.13_G. I have no idea how it was hacked and if that even matters. Based on this tiny amount of information can anyone tell me where to start as I would like to update it to 1.1.1 or 1.1.2 and if this is even possible.
