I've entered my Facebook login details via Home->Menu->Settings->Social Networks. I can see that this has been successful because my Facebook photo is now shown on "My contact card" under profile. However, when I go to a contact (who is a friend on Facebook) in the People app, then to the "Updates and events" page, then click on "Link Facebook profile ... choose from friends", no friends are shown in the "Pick friend" screen. Instead this just says "Friends data is either downloading or unavailable." If I click Menu->"Update now", it then says "Contact list is empty"
