I've got Customize on my 1st generation 2.0 iPhone. I am unable to install Winterboard as it stopped my phone from booting and forced me to restore.

I'm interested in applying my own wallpaper to the icons screen, but I don't know where to stick it. I am not interested in using the wallpaper from another theme.

Does anyone know where I can put a wallpaper image via SSH to allow me to apply it through Customize?
