Hey everyone... So I had an iPhone 3G that was running 3.1.2, and I wanted to downgrade to version 3.0 so I can use tethering hack from help.benm I downloaded the 3.0 firmware, plugged in my iPhone, held Shift + Restore button and selected the 3.0 firmware from the folder it was in. iTunes went through the whole process, and just as it's finished I get an error on iTunes saying and unknown error has occured and I'm back to square 1, except with a blank phone that only shows the 'plug into iTunes' picture. Why won't it work??
