Whilst syncing the iPhone to the iMac through iTunes, all the calendar entries on the iPhone were deleted - despite everything else (photos, music, contacts) remaining both on the iPhone and were imported onto the iMac. I have now lost my entire schedule, and am desperate for some help. Did the iMac clear the iPhone of its calendar, by replacing it's (empty) iCal contents onto the iPhone? Is there anyway of retrieving the calendar entries? My iMac is backed up on the Time Machine, but so far I haven't managed to find the deleted stuff anywhere!
