I have read about this via the BBC Red Button service a friend told me there is a opt out setting on Whats app when the contacts page is on screen click the 3 dots on top right of the screen Select Settings then the next screen has a option to opt out well checked and there is no opt out screen. I have noticed though they also told me I must have the latest version of whats app (4.4) installed is this correct? as I don't want my data and phone number on Face book and would think many other members who now know about this now would feel the same TIA
