Help, Can't figure out how to browse for the firmware

[Toymaker]

I just got a used iPhone 2G for my wife. It came with the 2.2 firmware already on it and I'm trying to run QuickPwn for Windows. It connects just fine but when I get to the second screen it asks me to browse for the IPSW firmware. I don't know what I'm looking for or where to find it. At first I assumed it would try to look on her iPhone but it doesn't show up as a drive, so I guess that's not what I need to do.

What am I missing?

Thanks.

It in your iTunes folder on your computer (providing you've downloaded it.)
