Following in the footsteps of Twitter, it appears that Apple is planning to deeply integrate Facebook into the upcoming iOS 6.
MG Siegler reports:
But Facebook integration will be very important for iOS — tons of apps use Facebook for sign-ups and authentication (many use Facebook as the only way to do this, to the dismay of some). Apple was undoubtedly watching this activity and realized that it was time to formally bring Facebook on board.
One thing still being hammered out according to our sources is exactly how sharing will work. Sharing is the other big part of the iOS/Twitter integration, and will be important for iOS/Facebook integration as well. But Facebook is significantly more complicated than Twitter in that there are all kinds of permissions for what you can post where and who can see what. And Open Graph adds another layer of complexity to all of this.
