Is there a theme (I assume this would be a theme and not a tweak) that lets you remove the background in the lockscreen? By background I am referring to the black gradient under the clock/slide to unlock buttons. I remember having one a while ago, but having just jailbroke 5.1.1 I can't seem to find any. When searching I just find themes that hide the clock completely. I still want the clock, just not the background that goes with it.
