Summerboard allows you to change the icons, background, dock image, and status bar (top bar) on your iPod. Once you install the program, you just go into the Themes folder, make your own, and place the files in. The Status Bar and Background go into the folder itself, while all the icons are in their own folder labeled "Icons". To make sure you have the correct names, just use another Theme folder in the Summerboard as a guide. All of the files have to be .png's, a type of picture format.
