LSBrightSlider is a new tweak released during this night in Cydia and it allows us to manage the brightness of our iDevice's screen very simply and easily. Practically, the tweak adds a slider to the LockScreen with which we can change the brightness of our screen, the slider being added below the one that manages the sound in iOS. Activating the slider is done by double pressing the Home button, the method being identical to the one by which the button for opening the camera in LockScreen is activated.
This tweak allows you to have a brightness slider in your lockscreen under the default volume slider that appears when you double-click the home button on the lockscreen!
LSBrightSlider is available for free in Cydia's BigBoss repo.
