Amazon just released a new Kindle DX which can now works outside the US using the GSM network.
It has a new device id and 3rd party packages written for the previous Kindle DX won't work.
It's really just a matter of repackaging them and the OS is virtually the same.
So I updated the packager to support this new device ; and repackaged the usbnetwork and screen saver hack package..
Packager (version 0.8):
USB network (version 0.11)
Screen saver (version 0.1)
