Figuring stuff out

When updating my iphone 2G with the new 2.2.1 firmware I was required to run QuickPwn after doing the update but could not get it past "QuickPwn is about to run on your iPhone"

There was a USB related update in OS X 10.5.6 which makes it so the iPhone is not detected when in DFU (restore) mode.  You can either go through the process of using some old 10.5.5 drivers from Apple ADC for the update then reinstall the 10.5.6 drivers or just plug your iphone in via a usb hub.  I had a simple VAKOSS non-powered hub and it worked fine.

If you have not jailbroken your iphone before you may want to use PwnageTool to select specific packages and create a custom restore image.
