So, in the Facebook iPhone app, I synced the contacts with my Address Book, thinking that it would only download the Facebook profile photos for my contacts that I already have in the phone. Instead, all of my Facebook contacts were added to my Address Book on both my iPhone and Mac, which I don't want. I'm getting stupid notifications for people's birthdays, people that I don't really know or care about. My iCal is stuffed and my phonebook all of a sudden has a thousand people with only the link to their Facebook profile, no phone number, no email or anything useful. How do I get rid of these without erasing my complete Address Book?
