I'm a windows user so I had to rely on a pre-made custom IPSW. Turns out I got ahold of an unactivated version of the file instead of an activated one. I guess I should have done more research before I attempting. So I'm stuck with my iPhone in emergecy mode. I'm not sure how to fix this problem... I tried downgrading to my old custom 3.0 IPSW using DFU mode and iTunes, but iTunes fails telling me it can't verify the IPSW. Possible Options: - Somehow downgrade back to 3.0. I'm pretty sure my modem firmware wasn't upgraded, so I think it's possible, but I don't know how. - Borrow a friends ATT SIM, then install ultrasn0w, then hopefully my TMo sim will work? - Find an activated version of a custom IPSW and try DFU mode installing it. But I don't know if you can do that (3.1.2 -> 3.1.2) At this point, I'd be happy just go back to where I was at 3.0. Anything really to get my phone working again. Does anyone have any suggestions? I really appreciate the help!
