ColoredKnob is a simple new tweak in Cydia which lets you change the color of your ‘Slide To Unlock’ arrow on your iOS device’s lockscreen. By default, when you visit the lockscreen you see the stock Grey colored arrow at the bottom but with ColoredKnob, you can change it to Red or Green. If you don’t like it, you can alway go back to the default Grey. Once the tweak is downloaded and installed on your device, you will get a new tab inside Settings.app which will allow you to change the arrow’s color (I like the Red one).
You can download ColoredKnob from the Cydia store via Big Boss repo for free.
The tweak works with iOS 5 devices only. As always, you need to jailbreak your device first in order to install this tweak. To do so, simply read our easy tutorials on how to jailbreak your iPhone 4S using Absinthe or CLI, untethered on iOS 5.
