I was wondering how facebook sync worked as well. There's still no facebook account to add in settings > accounts. Not 100% sure I want facebook sync, but it was nice that it grabbed fb photos. Didn't like how it made multiple accounts for the same people. So a) how do you get fb sync to work, and b) is there someway to merge contacts?
I use haxsync, it works well
