As if you don’t already have enough of an incentive to not drop your shiny new iPhone, a new jailbreak tweak will give you one more reason by programming your iPhone to emit a blood-curdling scream whenever it gets dropped. Via 9to5Mac, the new tweak uses your iPhone’s accelerometer to determine when the device is falling from a certain height and then lets out a scream to alert you to the fact that it’s in freefall.

The tweak’s developer has also just released an update that will let you add custom sounds to use when your iPhone is being dropped while also changing its settings to make sure that it works more consistently. You can find the source code on GitHub by clicking here and you can also find a looped video demonstration of the tweak embedded below.
