I was able to sync my google accounts on the PE, but not on the EE. I wonder if it's because I'd installed MailDroid on the EE? I'm going to try clearing the data app for the calendar and Froyo mail. Maybe that will clear it up.

ETA: I was able to set up my gmail account on the EE after clearing the app data, but not the calendar. When I go to menu -> calendars there's nothing in the list, not even "local calendar." And yet clearly there is a local calendar. When I did the same thing on the PE I had two calendars in that list: local and corporate.
