    Dhowett's iboot patch : http://dustin.howett.net/itouch/verbose_iboot_2.2.1.img3
    A NOR Flash Firmware

    1.Download DHowett's iboot patch and rename it to: iBoot.n72ap.RELEASE.img3

    2.Open up your NOR flash firmware with winrar and go to: Firmware>all_flash>all_flash.n72ap.production and drag DHowett's patch in.(Backup your iboot first to avoid problems.)
    3.Turn off iPod and unplug from computer
    4.Hold home and replug and continue holding home until iPod is in recovery mode
    6.Restore to your NOR flash firmware with the custom iBoot

    Yay you have verbose boot!

    Here is Dhowett's post on this explaining some issues.

    That's actually pretty awesome... Will this work for a 1G as well?

    You can kill steps 3-6 by just turning off your ipod and unplugging it, then holding home and plug it back in and keep holding home until it goes into recovery mode...I think it works the same way and doesn't give any errors when doing NOR restore(I've done it successfully twice).

    You could make it work for the 1G by decrypting a stock iBoot and the patched iBoot in the first post, then comparing them for changes (I like VBinDiff, personally).
    When you've found the changes made for verbose boot (and documented their offsets, although I also like to copy the whole line displayed by VBinDiff that changes occur in, just for reference so I know I'm working with the same code), open a decrypted 1G iBoot in a hex editor, make the correct changes, then resign it (which can be done with xpwntool iBoot1G iBoot1Genc -t iBoot1Gorig -k thekey -iv theiv, which is obviously just a generic example).
    Then, repack it and give it a shot.
    You could also possibly send it without restoring to it, just to make sure it works.
    This assumes that you know how to use the Pwnage2 exploit (if you don't know how, use geohot's iran, then send over the patched iBoot and try fsboot.

    Can I use this with a full FW too or do I need to use a NOR-only FW?

    It enables Text-Boot, so you'll see the exact comments which the ipod runs instead of a boot logo...
    It's only useful if you've a boot error, but I personally like it
