Dont know if its already been done. But I Ive attached an image to replace the black iPod nano thats used as the background for the wps simulator.
I have a white nano so I always wanted one to match the sim.

So if anyone else wants a copy, after downloading the UI256.png, change the extention to UI256.bmp, then replace the original in your sims folder.
Type
./rockboxui --background and viola. A nice pristine white nano.
