Kill Bill theme for iPod Touch.
to get custom docks working copy Dock.png to
/Bundles/com.apple.springboard/
and rename SBDockBG.png and make a copy in the same folder named SBDockBG2.png then transfer to iPod/iPhone, only then will custom docks work.
Edit: Also, you must edit Dock.png to be only 41 - 45 pixels in height for everything to look right.
