Newb Question- how do I install firmware from the invalid sim menu

I have a 1G phone that I was upgrading from 1.1.1. I went to install the firmware that is need for Quickpwn but an error happened when it was installing so I had to restore and install the latest Apple firmware. Now I get the "SIM card in iPhone does not appear to be supported" menu. How do I install the firmware needed for Quickpwn from here?

Thanks a ton,

Fuzz

I figured it out. Just put it in DFU mode: hold the home button and the power button for 10 seconds. Then, you will have to release the power button and hold the home button for 10 seconds to enter DFU.

Then hold shift and click restore in iTunes to install the ipsw you want.

Cheers,
