iPodEditor

iPodEditor brings the Mac to the power of editing the iPod's interface. Everything from text to pictures you can now edit with iPodEditor.

iPodEditor supports a wide variety of iPods, such as 1-5.5G iPod, 1G iPod Nano, and 1-2G iPod Mini.

It uses iPodEdit as its core tool for extracting/writing resource to/from firmware, and ImageMagick for converting images, so you can edit them with Photoshop or any other picture editing program.
