A lurker that finally had a question. Most of the time I can just search and find what I need on here but I am stumped this time. Received a 3Gs from a friend that got phone from work and didn't need the iphone. Problem- He used to get a white screen every now and then. He would have to force shut down with 2 button hard stop. Phone would work just fine. He sent the phone to me and all I can get is a whiteish screen. I hooked it up to my pc to charge and my pc did find the iphone. I did a restore and brought the software up to date but all the phone displays is the white screen. I'm thinking it is a hardware problem as the phone talks just fine to my computer, just can't do much with a white screen on the phone. Does anyone know where I might be able to send the phone to see if it is worth a repair? We have ATT store here and a Mac store would one of them be worth trying? I'm kind of at a loss deciding if it is worth putting any money into. I would do the $49 upgrade but I only have one coming to me and that will be used for another phone my daughter has. Thanks!!!
