Facebook integration with iOS 6 is quite great but you probably won’t like it when you’ve got thousands of unknown friends appearing on your contact list. The first time I did the integration, I was like WTF?! I got thousands of names on my contact list and when I launched Whatsapp, I had loads of contacts there as well. The problem was that it was rather hard scrolling through all the names to find who you actually want to talk to.
The first thing I did was to go to my phonebook and change the settings.
– Tap Groups at the top-left
– Uncheck Facebook and tap Done
This won’t totally remove Facebook contacts from Whatsapp, it’s only going to hide them from your iPhone address book. You have to go to your phone settings to totally remove those unwanted FB contacts,
– Go to Settings > Facebook
-Scroll down to Contacts and turn it off.
After doing this, I had to restart my device, then launch Whatsapp. I pulled down the contacts list to refresh and the whole Facebook contacts previously appearing were all gone.
