This is not an article on how to use your Kindle’s internet connection with your computer. We’ll let [Jesse] explain why:
This is not a tutorial about how to use the Kindle 2′s Sprint connection from your computer. I don’t know that it’s possible to do so without making changes to the Linux installation on the Kindle. I do know that abusing the Kindle’s Sprint modem like that would upset Amazon a great deal. Bear in mind also that Amazon know where you live. They know your Kindle’s serial number and thanks to the built in GPS, they know where you are right now.
What this is, however, is a nice tutorial on how to connect your Kindle to your computer so that it can use your computer’s internet connection. The instructions assume you are using a Mac, so you may have to adapt it if you aren’t. Basically you put the Kindle in Debug mode and tell it to use the USB tether for it’s network connection. This should allow not only a faster connection, but possibly a chance to see what exactly they are transferring back and forth.
