I got an iPhone today, and I plugged it in to my Mac. I have a Touch that I hacked with ZiPhone a while ago, and when I first plugged in my iPhone to my Mac, a screen appeared that said "Set up Your Phone" and it gave me a couple of options, one was to set it up as a new phone, and the other was to restore from a back up of my Touch. With out thinking I chose to restore from the back up of my Touch. I then realized what I did, and then clicked on the update button (the iPhone had 2.0 firmware, and I updated to 2.1). Then I downloaded Pwnage Tool 2.1 and went through all the steps it told me to, and when I go to restore the iPhone with the custom firmware it makes, I get an error 1600. This happens every time, and I have gone through the steps in Pwnage Tool to make the custom firmware at least 5 or 6 times. HELP!!!!
