Torch is a Cydia Tweak which will add a button to activate LED Flash. The button is located on your Lockscreen right next your your clock. It's a small button which take up space which wasn't previously used by anything, unless you have Lockscreen Seconds installed. In any case, you can just tap the button and turn your iPhone 4 or iPhone 4S into a great flashlight. No need to waste an Activator action or open up a third party application. This one's a keeper. Torch can be found for FREE under the ModMyi Repo in the Cydia Store.
