This is called iSaber that'll make you a Jedi.
I've recently modified an iPhone application which was the iFartz.
SSH into iPhone and place iFartz.app into Applications Folder.
Be sure permission are set - type: cd /Applications/iFartz.app; chmod -R 755 *
Restart iPhone (or recycle SpringBoard)
Start iSaber - Shake Phone - Enjoy - The force will be with you
