! Unexpected Error !
This is an error that I received on my Macbook late 2006 model. Redsn0w0.9.6b4 skipped DFU mode and gave me an unexpected error during the jailbreak process. I did a bit of research and found no real answer other than to try another computer. As you can see, thats what I did and it worked using a 27" iMac. You have to remember that this is still in Beta...

Thanks George
