Can anyone please help? My 'accounts & sync' settings have always had 'facebook' turned off for syncing, and I have never turned it on. Yet this morning i was playing around with the bit in 'people' to try and see if the facebook bit in there worked and i would be able to link a contact in there with their facebook account. It asked me to log into facebook (after which incidentally it could not then find the contact in facebook lol). After that i went to the calendar and it now shows ALL 2500 facebook contacts birthdays!! Please tell me there is a way to undo this. at no point did i ever select auto facebook syncing, or choose to import facebook calendar. Obviously now the calendar is pretty unusable as there are multiple bithdays on every day. Can it be reverted? Please help!
