Symptoms

When moving an event from one calendar to another as follows:

1. Launching the Calendar app on an iOS device that has a MobileMe account set up with at least two calendars (such as Home and Work).
2. Selecting an event in a Home calendar.
3. Moving the event from Home calendar to Work calendar.

You may see:

• Calendar events duplicated on me.com/calendar or in other applications syncing your calendar data (such as iCal or Outlook).
• Calendars out of sync on me.com/calendar or in other applications syncing your calendar data (such as iCal or Outlook).
