Are you sick of reaching for the sleep button? I know I am very much so. SpotLock is a free cydia tweak for iOS 5 which locks the idevice by swiping the device to spotlight. I really never used spotlight very much anyway. I think I will get more use from SpotLock as opposed to using spotlight to search for apps or other things. The best part about SpotLock is its free. So try it out and let us know what you think in the comments below.
