I need help here. Phones seem to know when to die all at once. Out of nowhere it says "insert smart chip" and will not allow me to do anything. 352735015269835 if anyone can help with a code to get it working again. Had this phone 1 1/2 years now, never done this before. Thanks!
Sorry, forgot to mention it was Cingular, still Cingular sim card, but has been working since they changed it all back to AT&T.
