    Hi,

    -if you don't have your SHSH files saved for 3.1.2 there is no way to downgrade to 3.1.2 on your 3GS....
    -if you use limerain you will lose your unlock for as far as I know, so you would need an original sim to unlock your phone again
    -best option in my eyes would be to wait until sunday when a new version of pwnage tool will be released which will allow you to upgrade safely without updating your baseband (as dhamien said here in this thread here already:

    You need to look in Cydia and see which SHSHs you do have saved. If you any of versions 4.0/4.0.1/4.0.2 you can restore to that version and jailbreak with limera1n and then unlock by installing ultrasn0w from within Cydia.

    On how to restore using those SHSHs, you can search for a guide or you can read this article made by Saurik. It explains what SHSHs are and how to use them. You can find it here: Caching Apple's Signature Server - Jay Freeman (saurik)

    Beware though, do not restore/upgrade to 4.1 as you will lose the possibility of unlocking for a long time to come.
