Check out this awesome jailbreak tweak! It has Facebook integration similar to the iOS’ built-in Twitter integration. It’s not rocket science. It’s simple to use, and it is also integrated with other social network sites.
The jailbreak tweak is called Fusion. What’s amazing with this tweak is – it integrates Facebook, Foursquare and MySpace into the default Twitter composition pane. Now you can update your status simultaneously. That’s not all. Fusion allows you to compose messages and Twitter updates using Siri.
Just say it, and Siri will do it for you.
