Concerning aupd:

I notice that when I updated the firmware with iTunes, the version of  
Diagnostic mode (see http://ipodlinux.org/Key_Combinations for  
information to access to this mode) changed.

When I downdated (put an old firmware) the version didn't change. This  
happen after I put the id flag of aupd entries (see p 11
http://www.linux4nano.org/drupal/files/hardware_synth.pdf).

So I think aupd allow to update some parts of the bootloader but not at all.

Does anybody have more information on the role of aupd on the previous  
version ?

Concerning cryptography :

I also notice that XOR 2 osos gives a high-entropy files. However, RC4  
is a generator of random bytes xor with clear text. So if we make :

osos_encrypted_1 xor osos_encrypted_2 = (osos_clear_1 xor key) xor  
(osos_clear_2 xor key)
= osos_clear_1 xor osos_clear_2

Does anybody know a stream cipher that allow to reuse the same key ? I  
mean that the next encrypted char depends of all the previous char  
encrypted and not only the number of encrypted char (such as RC4)
