Jordan Kahn of 9to5Mac reached over to Facebook and was told it’s part of the social networking giant’s decluttering effort which was designed to remove “phone book entries that were not useful.â€
In other words, Facebook is trying to remove some of the spam from your iOS Contacts app by no longer syncing friends that have no useful contact information.According to a Facebook spokesperson, friends that have no contact information on their profile other than a @facebook.com email address will not be synced to the Contacts address book going forward.
But do you know something ? This is a great and useful feature that I would love to use it on my iPhone, I regularly sync my Facebook and Twitter contacts with my iOS devices and these useless entries with no information apart from first and last name have been driving me crazy.
So instead of replacing your existed contacts on your device, Facebook sync creates a new ‘Facebook’ group in the Contacts app. It’s a one-way sync: when your friends update their email address or phone number on Facebook, those changes will be reflected in your Contacts.
iOS 6 can also update your existing contacts with their Facebook profile names and photos: go to Settings > Facebook, scroll down to the bottom and hit the ‘Update All Contacts’ button.
