iPhone, iPod touch, MobileMe Sync
What is my experience before System Status indicates the issue is resolved?
Data that you have successfully synced from your computer to MobileMe will not automatically show up on your iPhone or iPod Touch. It may also appear that your data has been removed from iPhone or iPod Touch.
What can I do before System Status indicates the issue is resolved?
You can confirm that your data is still on MobileMe servers by logging in to www.me.com/contacts and www.me.com/calendar. If the data appears correctly on me.com, but does not on iPhone and iPod Touch, you will be able to retrieve the data again on your iPhone or iPod Touch after the temporary issue has been resolved, and System Status has been updated. Please wait and check MobileMe System Status in MobileMe Account or from the MobileMe Support site for updates on the server status. Please read further for instructions on getting your data back on iPhone or iPod Touch after the issue is resolved.
What should I do after System Status indicates the issue is resolved?
Once the issue is resolved, your data should appear again on your iPhone or iPod touch Calendar and Contacts applications. If it doesn't:
1. Restart your iPhone or iPod touch: Hold the power button until "slide to power off" appears. Slide to power off your device. After it is off, press the power button to turn it back on.
2. Turn off syncing for the affected data: From the home screen, tap Settings > Mail, Contacts, and Calendars, and then tap your MobileMe account. Move the slider to "OFF" for the data type that is causing issues.

4. Confirm that the data has been deleted on your device by opening the appropriate application(s) (Contacts, Calendar, Safari).
5. Turn on syncing for the affected data: From the home screen, tap Settings > Mail, Contacts, and Calendars, and then tap your MobileMe account. Move the slider to "ON" for the data type you want to sync.
