    Now that I have a 3GS upgraded to iOS4, is there any way to unlock it for sale? Somehow go back to an older OS etc?

    If you have your SHSH on file then you can downgrade your phone. Then, depending on whether you have an old- or new-bootrom phone, you can jailbreak with either Spirit or Redsn0w. If old-bootrom, you can then upgrade to a custom 4.0 firmware if you like.

    If you do not have you SHSH on file, then there is no way to jailbreak your phone at the moment.

    I'm guessing I don't, because I don't know what that is. Damn... then again they're (the dev team) always hard at work, right? So it should happen eventually?

    At the iPhone hacks section.
    All you can do then is wait for a new jb for 4.0
    When that is out then you can jb and unlock with ultrasnow.
