On Saturday, Facebook revealed that its Facebook Connect technology has gone live with several iPhone applications. That means iPhone users can sign into the apps using their Facebook logins, and then link them to their profile and news feed on the social network.As an example of how it works, music game Tap Tap Revenge 2 now offers the feature, meaning that when you play a song in the game, a message gets published to your feed saying (for example) “Stuart submitted a score of 121150 on The Sound of Settling by Death Cab for Cutie on Easy” with a link for other people to buy the game.Facebook Connect also lets app users check what their friends have been up to – as an example, a streaming music app with the feature might let them check what their Facebook friends have been listening to, while games let them compare high scores.
