So I've done this before, but for some reason it isn't working on Froyo. I took the pyramid_background.png image or whatever and replaced it with in image of my own.
The problem is that unlike before, this isn't working. All it ends up doing is making the options for the Neutral Network, Water, etc. live wallpapers disappear.
Any help is appreciated, just trying to get my old live wallpaper on Froyo.
