My Iphone 3 GS suddenly had a white screen of death and I tried everything to fix this. Eventually I restored my phone in Itunes, but now I am unable to use it until I jailbreak and unlock the phone. I am just looking to use the phone like an Ipod touch. What firmware would the phone have once I did the restore in Itunes. Prior to this it had firmware 4.0. What software and tutorial should I follow to do this. Appreciate the help and let me know what you think.
