The now-ubiquitous lock screen was implemented by Apple into its mobile gadgets in order to curb unauthorized use and prevent pocket dialing, but a new jailbreak tweak makes it possible to enter various commands while your phone is locked. LockGestures lets iPhone users communicate with their device by performing unique finger-tapping gestures, according to Joe White at AppAdvice.

“Once installed, jailbreak fans can launch applications, adjust their iPhone screen’s brightness level and more from the Lock screen, via a series of different gestures (such as three one-finger taps, or a one-finger double tap),” writes White in a recent article. “Obviously, the issue with this jailbreak tweak is that it allows users to interact with their iPhone handset even while it’s locked. However, because the multi-touch options are gestures, this could mean that users won’t accidentally interact with their iPhone’s touch screen.”

LockGestures is currently available for download through the Cydia jailbreak application store for just $1. The tweak allows jailbreakers to enable and disable gestures, in addition to letting them choose custom combinations of actions and end results (e.g. tap three times with one finger in order to lower the iPhone display’s brightness level).
