I removed socialite via root access, and i still can't get the facebook account to sync up like the motodroid does. I believe it is a conflict between socialite and the LG Home launcher. I think if the launcher was removed as well, the phone would go back to the default android dialer and phonebook. Then you could sync up like the motodroid.
I was wondering about this too, and I created a socialite facebook account (don't know if I'm saying that right), but now my facebook friends who are in my contacts list have been updated with their pictures and such. I think I also had to change some settings in Socialite once I set up Facebook. Tell him to try that if he hasn't already.
