hi i had trouble with this but eventually worked out the best way for me,some of the steps might be unessacry but just lettin u know what i did. first of all i went into Menu, Settings, Social Networks,logged out then logged back in.
then i went into someones contact who has facebook go to edit profile then untap on fb link then tap again to link fb profile.
u will then see no fb contacts in list then press menu and update now
it will come up with every name on fb account but no pictures straight away.
then press menu and update now.
for me it only brought the pictures up for the first 6 or 7 profiles.i then scrolled down to the next 6 or 7 pressed menu and there pictures came up.might do it straight away once u upate but i have very weak signal took me a while but worked.
hope this helped
