Ever since I installed the 5.0 OS for my verizon tour google sync says "Last Sync failed, please try again later. If the problem persists try signing out of sync and signing in again." I already tried that, no luck...
Did you do the OTA upgrade or did you upgrade via DM. I know that the OTA was MR2 and the DM version is MR2.5 and I believe has a fix for the Google sync.
