Hey Scotty.   I have noticed my iPhone is not properly syncing my calendar from my iMac.  It is supposed to do it without even plugging it into the computer, but it is not happening.  How do I check the settings to make sure it is set up properly?  Thanks!

Syncing your phone and computer via mobileme can sometimes be problematic. 10.5 and 10.6 handle syncing via mobileme a little different so it depends what operating system you’re in.

In 10.6 mobileme’s calendar syncing is handled via something called calDAV. If you have all your updates run 10.6.6 on the computer and 4.2 on your iphone, then you’ll need to convert your ical data to calDAV. Instructions here: MobileMe: Setting up iCal for the new MobileMe Calendar

Basically you’re moving your calendar off your computer and putting it into the cloud. It’s a tedious process if you have many calendars. Let me know if you need assistance.

In 10.5...try to restart syncing try the following steps:

Go to system preferences/mobileme and check that syncing is turned on for calendars. Now go to your phone and to settings/mail contacts and calendar and check the same.

If all settings are fine then you may want to reset the sync by going to advanced settings in system prefs/mobileme and re-upload the calendar.
Next, toggle off calendar syncing on your phone. You will be prompted to delete the calendar info on your phone. If there are no events on your phone that aren’t on your iCal then you can delete. If there are events on your phone that are not in ical then we’d need to do a hard wire sync. (This can get confusing).
