If the repeating event is created on the phone and it hasn't been synced yet to the web server, then there is a bug where you can't delete or change an instance of the repeating event. This case can be detected with mSyncId. If mSyncId == null, then the repeating event has not been synced to the phone, in which case we won't allow the user to change one instance.
