I just jailbroke my iTouch 2g iOS 4.2.1 with greenpois0n and have played around a bit with Cydia. I decided tonight to take it a step up and try to create my own theme. I followed the directions on this thread (GUIDE Theming in 4.X), using the posters advice for the wallpaper, lockscreen background, dock, wifi bars, and battery. However after loading it into my iPod with i Fun Box, it seems only the wallpaper actually worked.

Can anyone help me find what I did wrong?
