The aim is to see whether some different firmwares are released or not
(this is why we thought about different nanos options, etc...). If there
are, it could be interesting for us to compare them. It could possibly
help to understand how firmwares are encrypted.
This is why we have decided to see among list users if some differences
could be found through a not-so-complicated (;p) handle (hash sum). If
there are, then we will ask all the different firmwares for a more
advanced comparison. :)
Thank you for your handling :)

2. Dump the Apple firmwares partitions.

too complicated ;)
isn't firmware dumped from device exactly the same you can download from
apple.com ? (see
http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStore.woa/wa/com.apple.jingle.appserver.client.MZITunesClientCheck/version
or http://www.felixbruns.de/iPod/firmware/)
for me, for example, Firmware-19.8.1.2 , extracted from downloaded
iPod_19.1.1.2.ipsw produces the same hashes as the same version firmware
dumped from ipod with dd:
rsrc: 0xC16AC03C
osos: 0x3D6DFAC4
aupd: 0x49D58FA7
