So, I’m mucking around with jailbreaking my iPod touch. I’ve installed SummerBoard and am currently fiddling with themes. The Dock.png file is 91px high for the pre-installed themes, but only the top of the file seemed to be showing. After a bunch of mucking around, it turns out the touch only displays the top 40px of Dock.png files.
Just FYI for anyone else who’s wondering what the hell was happening!
Pretty slick, eh?
