Ive put together my own lil theme that I can change randomly from day to day. I take bits and pieces of what other pple have don to build my own. The invisible button x999x gave us makes it possible for the icons to appear hiden.
You either probably have the Theme Icons and Theme Dock swithed off or you need to shut your phone off and on again for it to take effect. Also once you turn your phone on again. It might go back to black wallpaper and plain dock but then just go into a program and back out and it will change back.
