Facebook contacts not syncing
I had previously synced my Facebook contacts with my contacts on my iPhone 5 but while scrolling the contacts i realized that some of the profiles were not synced even though they were there in my friend list on Facebook. Thinking of it as a technical glitch i thought that maybe if i delete my account from the settings menu and then re sign in to update my contacts it would solve my problem. I did the same and to my horror the sync doesn't happen. First i could link contacts and then unified info would show up but now this doesn't happen. It seems that those profiles Are not taken which are already in my phone...
Please help and thanks in advance
iPhone 5, iOS 6.1.4
