    I Know Most People Want To Downgrade Their Ipod Or Iphone To 3.1.2
    YOU DONT NEED SHSH BLOBS OR EDIT THE HOST FILE
    The Firmware Is Already Jailbroken
    THIS APPLIES TO
    IPHONE 2G
    IPHONE 3G
    IPHONE 3GS
    IPOD 2G MB

    IPHONE USERS ASK FOR A FIRMWARE THAT IS ACTIVATED OR NON ACTIVATED
    IPOD TOUCH 2G MB USER WILL HAVE 200MB IN VM INSTEAD OF 80

    FIRST - You Must Be JailBroken On Ios4 If Your Not Then Find The Simpleliest Way To Jailbeak it

    Second - Just Google For Links to Firmware It Will Be Three Firmwares Parts Just Extract All 3 Parts to One Folder And It Should Come Out To 1 Firmware

    Third - Put Your Ipod In Recovery Mode (Just Turn Off Device And Unplug It Then Hold The Home Button Then Plug it in You Should Be In Recovery Mode

    Fourth - Your Device Should Show Up In Recovery Mode Now Hold Shift And Click Restore (Mac User Hold Command) Choose The The Firmware You Extracted And Let iTunes Do The Rest

    Pm Me Say Thanks if it Works
    No 3194 Error
    Good Luck

    I tried it and now I get error 1601 for some reason.

    EDIT

    The problem was I was trying to restore it in DFU mode. I took it out of DFU mode, did the shift + restore and and it showed the Sinful screen and it worked perfectly. Thanks for the help!

    This is the
    link I'm using and I was told to look for the "Pre-Jailbreak Custom 3.1.2 firmware from Sinful iPhone forums." Google that.

    Yes, after you jailbreak it using redSn0w restore (not in DFU mode) it using the downloaded firmware.

    and you're welcome

    Does it really matter what your post count is.......

    No, jailbreak IOS 4.0 then restore to the jailbroken 3.1.2 custom firmware.
