i have a 3GS with firmware 3.1.3 and jailbroken with spirit. i have been using facebook on it without any problems. when i tried to sync the friendlist on facebook with my contacts for the first time it crashed. it has been happening ever since even if i reply to any wall posts. i have turned off the syncing option with my contacts. but the problem still persists.. does anyone have any idea what might be causing this problem??
