Toggle LED Flash from the LockScreen. Only for iPhone 4 and 4S. Do you just hate it when the electricity in your house or any place goes down? And you need to launch the Camera App and then toggle flashlight? Some people do want to toggle the Flashlight super-quickly and easily. Especially in my country, where electricity goes down a dozen times. This tweak simply adds a flashlight toggle on the LockScreen next to the clock.
