PIM Data Reverting on Reboot
 

This has been happening with a few devices on two separate networks, so I can rule those out as being the problem.

Has anyone else ever experienced your contact information reverting to earlier copies during a reboot? For instance, I update a PIN for a contact, restart, and it reverts to the previous version.

I can delete the address book entry and then re-add and the new one doesn't revert as a workaround, but this is a pain.

Any one have any ideas?
