Aslock is a jailbreak tweak that adds new gestures to the lock screen. Normally a swipe down opens the Spotlight search, but with Aslock installed this procedure gets a boost. Two new shortcuts can be performed.
While Spotlight access can be preserved with the right settings, Aslock makes locking the iOS 7 device and opening the app switcher possible without touching a physical button. The process starts by simply swiping down on the home screen like normal.
Quickly swipe in the up direction and the app switcher opens. Alternatively, swipe down on the home screen and hold to lock the device.
If the Spotlight is a feature rarely used on your iOS device, Settings -> Aslock can be configured to hide Spotlight. Other options set the length of time until Aslock's functions are triggered to customize the experience.Aslock is available on Cydia from the BigBoss repo for $0.99. Jailbreaking iOS 7.1.x is now possible with Pangu. Check here for instructions on how to jailbreak iOS 7.0.x with evasi0n 7.
