I think I found the solution. For a week it wouldnt sync, I tried EVERYTHING suggested and nothing helped. This is what I did last night AND IT WORKED. Go to accounts and sync and delete your facebook account if you set 1 up. Reset the phone. Go to contacts-menu-get friends. Add your facebook account and set it to sync every hour. click get friends, put your phone down and go to sleep, I had the phone plugged in and connected to the wifi. When i woke up I had all the contacts! hope it helps, try this tonight
