My Mac's iCal does not sync to my iPhone or ITunes
I just bought an iPhone 4 about three weeks ago and synced it to my PowerBook (ppc) and it synced all my calendars. Then a week later I made changes and even deleted calendars and cretated new ones in the iCal on the PowerBook and it won't transfer those changes to the iPhone when I plug it in. The iPhone and ITunes still have the old calendars.
iPhone 4, iOS 4.3.2
