You can always extract firmware contents after installing my usbnetwork update. It's safe - I don't modify any existing code or scripts.

No, my Kindle is registered. I use usb networking only for hacking, not as a replacement for wispernet - it's safe

Google for kindlepid.py - there is plenty of info. In short, book is encrypted by Amazon using a key (PID) which is derived from Kindle serial number
