I'm in the exact same boat with my 3gs. Same modem firmware and 3.13. Can someone please answer? I'd really appreciate it too!

As far as what I have seen, you can not upgrade a Spirit jailbroken phone to a pre-jailbroken firmware. If you want to stay jailbroken, just leave your phone alone until a new Spirit or other jailbreak solution is released for 4.0/4.0.1
