    Do you have the shsh blobs saved for that phone? If not you will always get that error when restoring to firmware apple is no longer signing. You may have to go with 4.3.3 if no blobs saved.

    The location of the hosts file on xp is

    Csystem32\drivers\etc\hosts

    Open with notepad and put a # (number sign) infront of any line in the file that has gs.apple.com save reboot and restore/update to 4.3.3. You should be go to go from there. Redsn0w 0.9.6rc16 will jailbreak it for you after the restore.

    No need to run TU since your going to 4.3.3. Your going to lose setting etc from jailbreak apps unless you use pkgbackup or something similar in cydia. Then just run redsnow and install cydia.

    If your file is downloaded as a .zip file, just rename the ext from .zip to .ipsw
