Ok so I just tried to update to 3.0 all was fine and It was installing on iphone then the phone froze? When I try to sync it to itunes I get an error message saying(-9807)there was an error with itunes. But Now I cant use my iphone it just displays and emergency call screen. So I've tried to turn it on/off and my mac on/off numerous times, rebooting everything possible.... No luck So now I have no 3.0 and more importantly no phone! Any ideas what I can do to make it work?
