I read through the FAQ at the top, but i'm a little confused.. When i got my iPhone a few months ago, I went ahead and ran ziphone on it, without really knowing what I was doing. So i downloaded some hardware app on the phone that says my bootloader is 3.9... So my question is... When someone breaks the 2.0 Upgrade, what will I have to do. If i plug my phone into iTunes, and hit restore? Will it return it to its out of box condition. Or have I changed my bootloader? Basically what do I need to do to prepare it for the 2.0 update? Thanks all!
