I've got an original iPhone/iPhone 2G, and I'd really like to downgrade it to iOS 1.0. I tried Google, and I found many guides on how to do this. Some are really easy, but some are long and complicated. What is the easiest way that actually works? I'd appreciate someone who has done the process to link me to some working instructions. Thanks so much! P.S. I know that it's actually called "iPhone OS" or "OS X".
