I recently was resetting my passcode right after the i06 update and the phone went to sleep during the reset. When I turned it back on the only 2 passcodes I have ever used didn't work! The phone was disabled. I has to restore, but my computer I had my previous sync with crashed last week. I had to restore with my laptop and no settings or data were replaced on the phone. I lost 1000 contacts!
Anyway I can recover the last sync (maybe have someone repair the old computer and restore it to the old backup on it?). Thanks!
