Before I start, I just want to let anyone and everyone know that I am a complete newbie when it comes to this website and forums. So if I do something wrong, I apologize

My question is about my facebook contacts syncing with my LG Vortex. I know how to sync it but my phone doesn't seem to keep the contacts but maybe a day or so. They just disappear. I end up having to go into my accounts/sync and delete and re-do the facebook account. Any advice would be awesome. thanks!
