It looks like the pictures are off facebook, but it this the fbook app that is doing this?
It confuses be because for some people their numbers are not on facebook, so does it check their name from the contact? At the same time their are contacts with no picture but has the same name as my friend on facebook.
Is anyone else noticing this? try looking through your phonebook if you have facebook
UPDATE: okay, so it looks like it is pulling facebook pictures if it matches the EXACT name in your contacts....pretty cool
