    With what little information you provided I am going to say, no you can't jailbreak it.

    However, if you answer the following questions and give us more information then it might be possible.

    1) were you jailbroken before?
    2) did you save shsh blobs for earlier firmwares?
    3) what bootrom do you have?
    4) assuming your 3GS is factory locked do you have access to an official sim card?
    5) pc or mac?

    By official sim he means the one that you used to activate your phone with when you first bought it.

    I am on same firmware as you. 05.13.04 and I cannot jailbreak yet so i doubt you will be able to jailbreak.

    Someone pleae correct me if i am wrong.

    If you don't have your shsh blobs then you can not downgrade. If you can not downgrade then you can not jailbreak.

    Be patient, allegedly comex is close to releasing a jailbreak for iOS 4 and 4.0.1.

    Note, I asked what bootrom you have, not modem firmware. They are two entirely different things. However because you don't have your shsh blobs backed up knowing your bootrom doesn't help.
