I thought this was a known fact. Isn't there numerous articles were people were surprised how Facebook knew and was recommending their dentist/plumber/clients to be added? Towards the end it turned out to be from the contact list uploaded from the user's phone. I am not going to say to avoid FB, but if you really want it on the phone, please use a non-official version for privacy sake. Atleast on android, they are less sucky than the official version. One of those times I am happy a company doesn't make an official version for Windows Phone and the MS version doesn't suck.
