Facebook SDK 3.0 for iOS hit beta a few weeks ago, but it looks like a finished version has popped up onto the surface of the Internet. The SDK continues to push a more iOS-native experience, better API support and better session management.
iOS 6 integration won't get the eye down until Apple pushes out their latest software update, with Facebook keeping a separate beta track active to serve forward-thinking developers. Facebook's regular users won't be getting the same reward, though. Mobile ads are peeking their head into the latest beta, it seems and while Facebook isn't pushing them big time [yet], it's a sign of things to come.
The social network is letting developers pitch their Android and iOS apps from Facebook's mobile portals, with a quick jump over to the relevant app store if the title isn't already loaded. At the moment there's no ETA, but with the mobile ads, I'm sure Facebook junkies are in no rush just yet.
