I think it keeps the facebook info for people who are in your contact list before you synced with Facebook. But it removes the people you did not have in there.I've switched Facebook contact group and birthday calendar off on my iPhone a million times but it keeps turning itself back on. Is this a known problem or does anyone have any suggestions to resolve it?
I was annoyed by this so I haven't quite followed the scientific method so I don't know if it requires everything here but the last steps of allowing FB access to your cal and contacts is needed to fix the issue. I don't particularly want much from Facebook on my phone and everything here seems to do that for me.No I mean I turn it off and like a day later it'll be back "on" again and my calendar will be flooded with birthdays and my contacts my whole list of FB friends.
