I just used pwnage tool to attempt to jailbreak my iPhone 3G on my new unibody macbook. I was all the way through to the end until I realized that the new macbooks and new software do not recognize DFU mode on the iPhone.

I found a link with a program automator script that fixes DFU and sets it back to 10.5.5. After installing it, everything went smoothly, my computer rebooted, etc etc.

However, I still cannot get my iTunes to restore my iPhone with my custom ipsw.

I'm going to try to pick up a USB hub later today. 2 questions.

1. How do I remove this Fix DFU 10.5.6? I just want my computer back to normal.

2. Once I get a usb hub, is it possible to simply click on "restore iPhone" while holding the alt/option button to load the custom ipsw that pwnage tool created? Or do I need to go through the entire process again?? Or can I just set the iPhone to DFU mode and restore that way?

thanks a lot in advance!
