Fusion is a new jailbreak tweak available in the BigBoss Repo for $2.00. Fusion integrates four social networks together, allowing the user to update all four from one central location. The four social networks combined in Fusion are Facebook, Twitter, FourSquare, and MySpace. It also incorporates Siri, calling it Furi. Furi can be used to speak updates to all four of the social networks simultaneously. Fusion can be set to an activator to open, which makes using it even faster.
