I ask this because I tried with the instructions in the stickied post above and failed. I'm pretty sure I did everything I was told, but it was kind of confusing since I was wanting to unlock it and jailbreak it to sell it. I thought I selected the right answers, but when I got to the iTunes recovery and selected my ipsw file, it told me "no dice!" I'm worried about bricking this thing since there are quite a few ways to go wrong. I selected 2.2.1 for my original iPhone, downloaded the bl46.bin file. I just have no idea what I did wrong. Anybody got any clues?
