Aperture Battery Wallpaper Help

[DoctorManhattan]

I downloaded the "Aperture Science Battery" for my lockscreen, but then I accidentally set a wallpaper. Now it only shows up if I plug it in to the charger but other than that shows the wallpaper. Does anyone know how to fix this? I have a 8GB Black iPhone 3G running the 3.0.1 jailbreak.

I guess I don't understand. Battery themes only appear while its charging; however, if you take the image you want and name it "LockBackground.png" that will appear when its not charging, regardless of which wallpaper you select.
