Facebook contact pictures not updating
When you view a contact card, it "shows" you the merged info on that contact.
If I do "Update All Contacts" with Facebook and/or Twittor or allow Facebook to use my contacts, will this overwrite existing pictures? ) (For bonus points, please explain exactly what else will be changed.) Facebook contact sync will add photos to contacts that don't have any pictures assigned and leave those that have them already unchanged.

In my own experience, using the "Update All Contacts" creates new contact cards and doesn't change your contacts except the "Linked Contacts" field, which links your contact to his/her Facebook contact card.
