@NiLuJe: Very great job!
Maybe I am posting in the wrong forum but your work is the best I read about Kindle hack. I have a Kindle DX US version. Can I use only the jailbreak tool to enable the usbnetwork communication in order to "register" my Kindle and obtain the "Collections" feature? (I live outside Whispernet coverage area, like many others people).
Thanks in advance for you answer.
