I had already jailbroken my 1.1.5 ipod touch when I upgraded to version 2.1. When I upgraded, I lost installer.app, so I browsed around trying to find a way to jailbreak the latest version. I have spent all day trying to build the custom .ipsw file through Pwnage Tool 2.1 and QuickPwn, but when I try to build the file, I get the "sry, i haz fail" message, and when I look in the log, it says "failed to build custom .ipsw file." There really aren't many tutorials of QuickPwn or Pwnage Tool that feature a person actually jailbreaking an ipod touch. They always have an iphone. If anyone could provide some advice, or maybe just a good link, it would be greatly appreciated. I mean, I checked everything and I seem to be doing it all right. Usually, when technology fails in my home, I just assume that it is because I'm doing it. But maybe I'll have a chance at success through the bounty that is the internet.
