After I upgraded to ICS my google calendar will not sync with my phone.
The rest of my google account (browser, contacts, email, etc.) are fine. However, when I start the sync manually the circular arrows next to the calendar go around a few times nad then stop. They do not disappear.
I have deleted the account several times. I also delete the widget and clear the calendar data.
I even went so far as to re-install stock ICS (I am rooted) and even then the calendar would not sync.
