Did you make the mistake of connecting your Facebook contacts and your phone on the iPhone OS 6? Well after a bit of fiddling I figured out there is an easy fix.

Step One

Go to settings.

Step Two:

Scroll down and click on Facebook.

Step Three:

Scroll down to where it says allow these apps to use account. Slide contacts to no. It then takes all your Facebook contacts off your phone.

On a related note if you want to make all the Facebook birthdays unlink also, slide it to no.
