Facebook has announced Facebook Connect for the iPhone, which allows developers to add Facebook compatibility to a variety of iPhone apps. The new technology allows apps to share social information via Facebook across multiple platforms. Apps will be able to add Facebook's social aspects in differing ways. Facebook Connect will allow Urban Spoon and Movies by Flixster users to read and share reviews with Facebook friends. Who has the Biggest Brain will allow sharing scores of fellow Facebook users and a user's Facebook account can be used to locate friends using maps on Whrrl.

Game apps like Tap Tap Revenge 2, iBowl, Agency Wars, Binary Game and Live Poker will feature the ability to play against friends utilizing Facebook Connect. All nine apps have gone live with Facebook Connect ability, and more are promised in the coming days.

App developers who use of Facebook Connect will only need a few lines of Objective-C code to implement the technology. It will allow users to log into Facebook within the app, find friends and then share the actions, occurrences or information generated within the app with others.
