    But is it possible to downgrade an iphone 3GS with 4.01 on it to an older IOS like 3.1.3? Just curious. If it is possible, how would you go about it? Thanks guys

    Yes you can IF you have shsh's saved for the firmware you want to downgrade to. Here's a guide:
    Restore iPhone 3GS to 3.1.2 Using SHSHs on File with Cydia | Windows

    What if you havent? I take it the shsh's are unique to each iphone?

    Yes, they are unique. If you haven't saved them, you cannot downgrade.
