My wife has been hounding me about finding a way to hook a calendar to her 8703e that will OTA sync (BIS). I'm thinking that Google Calendar will do the trick, but am hesitant to try GCalSync because it's in beta, and apparently you can only add/edit calendar entries via WWW. They're saying that the ability to push updates/changes back to Google has been disabled (temporarily).

Has anyone had any luck with GCalSync? If so, hows it working out and what limitations have you found?
