My 650 seems to have gotten possesed while I was out trick or treating with my kids. The device has a lengthy hotsync with no errors, then requires a reset yet has no current data. Everthing from the call log, versa mail to apps themselves revert to 10/31 of last year. Some apps require reactivation to work while others (ie airline timetables) no longer funcion due to old data. Anyone know how I can stop this archaic loop and bring my 650 into the here and now?
