My Droid Incredible's data sync feature completely stop functioning on October 13th. I go to Settings ---> Accounts and Sync, and the last time everything synced was the 13th.

I've pressed the 'sync now' button and nothing happens. I've turned sync on and off, I've turned background data on and off. Absolutely nothing works.

The only notifications I get are for 1 of my E-mail accounts tied to the HTC Mail app. That's it.

Any fix for this or am I going to have to restore to factory settings?
