iPodWizard enables you to customize various icons, text strings and fonts on your iPod. It can either connect directly to your iPod and download the existing firmware for editing, or edit firmware from an Updater and then apply it to your device. You can scroll though the existing bitmap images (Apple logo, battery status, stars etc.) and replace them by using your own bitmaps, then write the changes to your iPod. The program also includes some additional tweaks as well as options to create and apply themes, downgrading firmware, extracting resources from Updaters and more, however these are mostly undocumented and should be used by experts only.
