Hey Guys, I was given a 1st gen iPhone, it came with no sim, and had a passcode. I restored it, and it's currently at 3.1.3. I want to unlock this and put it on another carrier, T-Mobile if possible. I've been reading guides like crazy, and trying several methods. So far, I've tried Spirit (which worked great on my Touch, but I'm getting an error and it isn't working.), RedSn0w, this appeared to work, even said it was installing the data on my phone post-installation, but it still won't go past the emergency call screen, and the only SIM I have is for T-Mobile. So I was wondering what I should do. Thanks.
