FINALLY! After spending days trying to figure out why I could not get past the "Error: no key found. maybe the PID is incorrect" and "Error: invalid PID checksum" error when using my PID from my IPhone, I found the post about downloading azw-0.2.zip and using that version of kindlepid.py and it worked! I can now grab some of my books from my phone and move them to my 360 reader.
