What is SBSettings?
Access the important settings and functions of your jailbroken iPhone/iPod Touch directly on your homescreen, or even on a running app.
To use, slide your finger across the statusbar. A window will drop down with the toggles for various processes, and more options are available when you tap on the "more" button. There is no icon.
You can only get SBSettings from the Cydia app store (on jailbroken iOS devices).
