As rumored, iOS 6 is getting Facebook integration, just like Twitter integration in iOS 5.
“We’re also making it really easy to post to Facebook from many of our apps. Post photos from Photos, post location from Maps… we’ve also integrated it right in with Notification Center. Anywhere you are you can tap to post to Facebook and Twitter.”
Siri is also having Facebook integrated. Even better, Facebook’s deep integration is now a public API, meaning any app can easily integrate Facebook into its app.
There’s even contact list integration. Facebook events and birthdays will now automatically appear in your calendars. And it’s also coming to Mountain Lion.
