So I've currently got iCal to sync (via CalDAV) to my Google Calendars. My iPhone then syncs to my iCal, obviously. However, I just got the 3.0 update and I'm a little confused about how to set up my iPhone to sync with my iCal/Google Cals via CalDAV. I understand you go to add account, other, etc. But then what happens to my existing calendars in the Calendar app? Should I just delete them all and replace them with new CalDAV ones? If I do that, what happens when I sync with iTunes (and iCal as a result)? Is iCal smart enough to realize that the CalDAV calendars I set up on my iPhone are the same ones as in iCal? A better question is, why doesn't iCal just automatically set up my calendars on my iPhone to be the same CalDAV ones it has? That would eliminate all this confusion.
