    When i try to restore it to 3.1.2, it keeps getting error 1604. I have a 2g itouch with 2.2.1 firmware. I already tried to put it into DFU mode, but still didn't work. I looked at all the other threads but they didn't help.

    So your on 2.2.1 and your restoring to 3.1.2. Did you not just click update, pay for it through iTunes and then update automaticly?

    Yes I am on 2.2.1 and trying to update to 3.1.2. I read that you're not suppose to update because it is wrong. It said that the only way to jailbreak is if you restore to 3.1.2 firmware.
