This may sound silly to you but after having being stuck with this problem for almost a year it is really starting to annoy me! When i got the phone, obviously downloaded a few apps including facebook. I had signed in and had not been presented by the sync facebook to iphone, my boyfriend however was and clicked yes signed in to his facebook.... It resulted in all his contacts and calenders from facebook all over my phone. I solved this problem with ease by selecting unsync. Thinking that i could then sign in on my facebook and have all my information... No not that easy.. I have no idea how to get rid of his original sync because it messes with me everyday on other apps and games (always signing in to his facebook). So cant play anything as me. I have tried almost everything except reseting my phone to factory settings as i have loads of pictures and numbers i dont want to lose. All i want to know is how to disconnect the main facebook sync..... NOT unsyncing the contacts etc. Thanks in advance!!
