'Slide2Lock' Lets You Lock Your Device By Sliding Down on the Home Screen
A new free jailbreak tweak called Slide2Lock
by iOS developer Suu is now available in Cydia that allows you to slide down on the Home Screen to lock your iOS device.
Using the tweak is very simple. You can just grab anywhere on your Home Screen and slide downwards, and your Lock Screen will suddenly appear; your device is now locked.
This is a handy tweak for anyone with a broken lock button at the top of their device that wants an easy way to lock their device without having to wait for the device to time out and auto-lock, unfortunately it will disable SpotLight search on the Home Screen.
Slide2Lock doesn't come with any options to configure, you'll be able to download the tweak and start using it immediately. If you'd like to try it, it's available for free right now in Cydia's BigBoss repository.
