When you synce your contacts with Facebook are the photos supposed to update automatically when your friends change their profile pictures? Mine aren't. I'm pretty sure I remember them auto updating on my old Nexus One, and maybe even my old iPhones? (3G and 4). Am I imagining things, or am I missing something? My 4S definitely displays old Facebook profile pictures when people call. I think in the past I have un-synced and then re-synced the contacts to update the pictures, but it seems it should do that automatically.
