Update iOS contacts with Twitter and Facebook
One of the better inclusions in Apple’s iOS 6 update is the integration with social networks Facebook and Twitter.
But apart from being able to post to these networks from within iOS itself, you can actually update your contacts with social networking information.
To do so, head to the Settings app, then scroll down to the “Twitter and “Facebook” options. Within each option, you should see the ability to sync with contacts, which will sync up photos and respective social media accounts.
