Okay, I had installed Jailbreak first like the post laid out and it had gone through the update process and then failed like it was supposed to so i assumed it was on there. Nevertheless, I tried to install it again and it gave me the error code 0003. I tried the screensaver hack again and it gave the same U007 error as before. I'm sorry if I'm just missing something fundamental but I'm really confused as to what I'm doing wrong. I am using the .bin files for the kindle3 (or DX non-international), dropping them in the root directory, and trying to update. I really appreciate that you've been willing to help so far....any other ideas?
