Duplicate Contact and Calendar entries in iPhone OS 3.0
I noticed something odd when thumbing through my calendar the other day on my iPhone. I noticed I had doubles of every entry in my calendar. I figured it was a sync issue so plugged it into my machine and noticed that I was syncing to the computer as well as to MobileMe. I figured things would get merged, but apparently they did not.
The fix was to turn off syncing of Contacts and Calendars in iTunes. Then turn off MobileMe syncing for Contacts and Calendars from the iPhone. Turn them back on and the you’ll be prompted to merge your contacts and calendars which you should do. When done, you’ll be syncing over the air, but not to your computer which should be syncing to whatever service you use anyway.
