Hello to all! I'm the owner of project Qindle. There is a new version of qindle(0.0.3), which doesn't need installation and won't affect the system. If you have usbNetwork installed, just download qindle from
http://qindle.googlecode.com/files/local.tar.bz2 and extract into Kindle's flash drive. Then, by executing `usbNetwork twice(the first time usbnetwork starts normally), the new system starts.
Sorry for the shortage of document, I'm working on it. Any suggestions are welcome.
