To uninstall the Rockbox bootloader, you can type the following command to restore your iPod to its original state: ipodpatcher -w N bootpartition.bin where "N" is the disk number of your iPod (found using the instructions in Step 1b below) and "bootpartition.bin" is a file containing the original contents of your iPod's firmware/boot partition. This file is created in Step 1c below. I haven't done this before, just for reference.
