    Download redsnow 0.9.6rc8 and a copy of a regular 4.2.1 firmware.
    Run redsnow, point it to a regular 4.2.1, then choose the option to just enter pwned dfu.
    Then restore to the custom firmware in itunes.

    If you want to unlock then ya, that is what you would have to do as your current baseband cannot be unlocked.

    If that is the case then do this:
    Restore to regular 4.2.1
    Use redsnow 0.9.6rc8 to install cydia and the iPad baseband.
    If you have new bootrom then you can run greenpoison on it after to untether it.
