Fixed the wallpaper issue on the 28004 ROM, should work on 21877 as well
Goto the following
http://forum.ppcgeeks.com/showthread...54#post1350854 and download the bg4all cab
then do the following on the Home Tab, Menu > Home Wallpaper > Picture Wallpaper and set the wallpaper to the EnergyROM Wallpaper in My Pictures.
I have the weather animation disabled on the Home Tab, so you may want to try selecting Weather Wallpaper above if you want weather animation. I haven't tested this, if someone does, post if weather animation still works on the Home Tab
