My situation: I have a 1.1.1 ipod touch, jailbreaked. It freezes up. I go to plug it into iTunes on my freshly wiped and reinstalled (since i downloaded the 1.1.1 update) mac running Leopard. Itunes forces me to download the 1.1.2 updade before it restores. I do this but it gives me the 1604 error. I really do believe the issue is that It (jailbreak, whatever) doesn't like the 1.1.2 update while restoring. Perhaps someone would be kind enough to share their 1.1.1 update file so I could back up to THAT restore and go from there. It is stored here. Of course if someone knows where to grab the 'old' firmware and it's already online somewhere please tell me where! Thanks in advance for the help.
