Fusion is a tweak that takes the Twitter integration of iOS 5, and expands it to encompass Facebook, Foursquare, and Myspace. You can also configure Activator actions to start doing different things like compose a tweet, post a Facebook status, and more. You can also configure an action that allows you to post a status to every social networking site, if you choose to. It also has an AssistantExtension plugin for Siri called Furi.

I did not make this tweak, nor am i responsible for the contents of it.

This tweak is available for $2.00 on the BigBoss repo.
