Hi everyone, I know all the rage right now is the 3G iPhone, but I need some information about unlocking the 2G iPhone and all the information on the net is watered down and scattered. I just purchased a used 2G iPhone that has been pre-unlocked. It is one of the original iPhones to have shipped, I believe. It is a week 25 iPhone. I'm very confused as to how I'm going to be able to upgrade to 2.0 firmware once it is released. Do I have to know how the iPhone was originally unlocked? Being that its original firmware was 1.0.0, is it safe for me to restore the phone using a firmware image other than that? Thanks for your help!
