Hi, I have been using an iPad for at least a year, and go nowhere without it. Recently, I upgraded my computer to a MacBook Air running Lion and my iPad troubles began. Syncing destroyed my calendar: Duplicates that could not be deleted, events erased. Called the help desk, they had no clue. (Why are there people on the Apple help desk who don't use Apple?). Stopped allowing my calendar to be synced which may or may not be good. Any ideas?
