ColoredKnob is a tweak published last evening in Cydia that allows iDevice owners to modify the slider button to unlock their terminal. Normally this button has the color white to gray and using the tweak you can change it, but the options are limited only to the colors green and red. Both colors are already used for this button and they are displayed when we receive a call or when we want to close the terminal, so basically the tweak replaces the normal button with one of the other two.
ColoredKnob is available for free in Cydia in the BigBoss repo.
