Since upgrading to OS 3.0, I noticed the behaviour in the Contacts app has changed. I now have two separate sets of contacts, one called "On My iPhone" and the other called ".Mac (MobileMe)". The thing is, both of these lists contain the exact same information, so when I go to "All Contacts", every single one of my contacts has two entries. Is there any way for me to fix this and get it to display only one instance of contacts? It's pretty annoying. I do not have iTunes set to sync contacts to the phone; it's all done over the air with MobileMe.
