My wife uses the iCal calendar on her iPad and now wants to sync it to a google calendar, which she has never used before. On my iPad when I type something into the iCal, it shows up on my google calendar, but hers does not work like that. Nothing shows on her google calendar. My default ipad calendar is set to my google calendar,but hers is set to ical. I'm afraid of loosing all her calendar data on iCal if i do this wrong, so how do I get them both working together without overwriting the iCal one?
