How to remove Facebook birthdays from iCal on iOS6 iPhone

This has been bugging me recently, as hundreds of birthdays appear on my ical now.... so I found a solution.

On you iphone go to:

settings > Facebook > (switch off all the apps allowed to use your account, then they dissapear from you ical on iphone.)

Hope that helps!

Update...

They vanished! Phew
