RetinaHaz3 ColorKeyboard and Zeppelin:
If you don’t know what these are than it most likely won’t matter. Colorkeyboard is a Winterboard like tweak that allows you to apply changes specifically to your keyboard, IE give it color.
Zeppelin is essentially the same thing but specifically for carrier icons.
RetinaHaz3 comes with a Colorkeyboard feature that can be enabled in Settings>ColorKeyboard. Likewise RetinaHaz3′s Zeppelin icons can be applied in Settings>Zeppelin.
