I've been desperately searching the forums with hope of finding a solution that doesn't involve losing the phone function of my iPhone. When I try to simply hold shift, click restore, and select a downloaded version of 1.1.1, I keep getting an error. I am assuming apple has finally attempted to stop downgrading, but if you guys can continually hack the iPhone, I'm sure somebody has found a way to safely downgrade back to 1.1.1 or 1.1.2.
