    I seem to remember you have the new bootrom and don't have a 3.1.2 SHSH.
    If this is right you cannot pwn it , cannot maintain your BB and cannot JB iOS4

    Sn0wbreeze is NOT made by the Dev-Team. And custom firmware files made with it or with PwnageTool will NOT work on a phone at 3.1.3 because such a phone cannot be pwned.

    Restoring to 3.1.3 won't do you any good. The 3GS can only be pwned at 3.1.2 or lower. 3.1.3 can be jailbroken with Spirit, but Spirit does not pwn the bootloader so it is not possible to load unsigned firmware to a Spirit-ed phone.

    For complete details on which phones can and cannot be upgraded at this time, see http://forums.macrumors.com/showthread.php?t=942632.

    Snowbreeze does not update the baseband. I would not use Snowbreeze, though. It's buggy and the author stole Dev-Team BSD-licensed code and made it proprietary. Not cool. See if you can get your hands on a Mac (or just a firmware made with PwnageTool 4.01).

    Yes, you are out of luck saving your BASEBAND of 5.12.01 as you cannot load a custom FW because you cannot PWN your phone.
    New bootrom phones cannot be pwned fullstop.

    If you want to be able to use your iphone unlocked dont update.
    You never know how long it will take to release and we dont even know if its even possible yet for that userland exploit to be used as a JB.
    If you dont care about the JB or unlock go to official 4.0

    If you are worried about apple updating to 4.01 before you can install 4.0 and JB it, save your 4.0 SHSH now.

    If you saved your 3.1.3 hashes, all the new ones will be saved automatically.
