Okay, this sounds promising! Now I'm sure I won't have to spend the
extra euros on the X5L. :-)

I just found a thread on the forum with someone who has one but is
afraid to open it up. Well, since I'm hoping to do some development
(which will void the warranty anyway), I won't mind to open it up.
Maybe not immediately, but when I got it for a while. Let's hope I
won't have to drop it first. :-D

Understandable. The firmware images available for download on the
iAudio website aren't enough for that, BTW?

Keys? Do you mean decryption keys? Sorry, I'm not very well-informed
here, even though I've seen most of the Rockbox wiki by now. Is there
any hacking document with more information about this process? How can
you read those keys even before reflashing the firmware? To me this
sounds like the typical chicken-egg problem, so I probably miss some
detail.

Okay, I just found the IaudioBoot page, looks good. So you can still
access the disk contents via the USB port, even when the on-disk
firmware is broken? Great!
