I have once opened a new facebook account. It requires me to enter a phone no. I used my mum’s no. After that, all my Mum’s friends that have my mum’s phone no. are shown in the friends recommendation.This imply that Facebook already has your phone no. from your friends when your friends use this contact sync function. Basically, you are uploading your friends’ privacy to Facebook, with no control on how they use it.
