Okay I've downloaded the 1.1.1 zip, because Im using it to downgrade from 1.1.2 I plug into iTunes, and when I click 'Options and Restore', it allows me to browse for the firmware. But "CHOOSE" is grayed, it does let me enter the Firmware folder, but all I see is a few other files. Shouldnt I be able to Choose the firmware folder? When I download the file, it's labled as a zip file, should I be renaming it first? If so, how?
