I've been having problems with my iTouch lately. I've looked at many sites (including this one mainly) for a ipsw file for jailbreaking the 1.1.2. I know how to downgrade, but when I update, I get an error saying it can't read the iPod. Then, when it did work, windows.bat wouldn't work at all. It would say the iTunesHelper.dll(?) couldn't be found. Is there something I've done wrong in my process?
