My screen has gone white on my LG cu400. It otherwise works, but I don't know the number sequence to save my address book to my sim card. Does ANYONE out ther know how to do it? (i.e. every menu item on the phone has a corresponding number to push, like messeging is #2 etc.) I just need to be walked through, and to be honest, I'm scared to death to loose these numbers because some of them I have no way to get back. HELP!!!!
