I have a A1200 Ming. When I use my Motorola phone tools to sync the calendar from Outlook 2003, the appointments or Holidays will be one day off. Independence day will be on July 3rd on my phone but July 4th on my Outlook. I know that July 4th was on a Thursday last year and a Friday this year,next year probably a Saturday. I entered a vacation day for a Friday on my outlook and it transfered to the Ming on a Thursday.
