I already download 2.2 firmware(2g version) to my mac notebook, i put it into a fold called "iphone" with quickpwn 2.2. But when i run quickpwn, it always starts searching 2.2 firmware, and says it can not find firmware. I want to know which fold i need to put firmware file in?

check the name of the ipsw,
the name should be
iPhone1,1_2.x.xxx
not
iPhone1_1_2.x.xxx
