I don't understand why there are two sets of calendars now. I show a set of calendars under the heading "On My iPhone" and the exact same set under the heading ".Mac (MobileMe)". If I view by "All Calendars", I see two sets of every event. If I add an event, I want it to show up in my iphone and I want it to update through MobileMe. To make things worse, it seems that every time I leave the calendar app, even though the last set of calendars I viewed was ".Mac (MobileMe)", when I return and begin adding a new event, it's reverted to the "On My iPhone" set of calendars. This just makes no sense to me.
