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.

Not only that, it seems they will match your phone number if any of your friends upload their contact list to Facebook.
