I want to remove official Facebook app from system because its a piece of crap, but I am not doing it because it syncs my contact with Facebook. I add someone friend and I get her phone no. and email id in my smartphone (provided her privacy settings permit it). It also syncs photos and missing data with existing Google and local contacts.
So, all apps which login using oAuth have problems with contact sync (correct me if I am wrong). I don't have problem sharing fb password to an app if it can do pure Facebook contact sync. Is there an app?
