So I tried iPwner with a new iPhone I got today as part of a warranty replacement. Now I've got a phone with a blank black screen that I can't seem to fix. When I try to restore and tell iTunes to use a new 1.1.4.ipsw that I downloaded, I get an error that says "iPod cannot be restored due to unknown error." AHHHHH now I'm really worried. I just want to get back to factory virgin 1.1.4 state. I have a legit AT&T contract and after this experience don't really want to risk it anymore. PLEASE HELP! Thanks in advance.
