I have a friend with an S2 running ginger bread. everything syncs fine except the calendar. All of the other things are showing that they have synced but the calendar which is tied to gmail always has the white sync icon beside it and it is not turning. It will manually sync with the check mark off and then on but wont auto sync. I tried clearing the cache of the calendar and then re syncing that worked once but wont continue to auto sync. Any ideas??????????
