    Factory unlocked or ultrasn0w unlocked?

    Assuming you're unlocked with ultrasn0w, you would have to create a custom firmware with redsn0w preserving the baseband.

    You could always purchase an IMEI unlock, which saves the hassle of unlocking and jailbreaking. It's permanent, and updating to a newer firmware is a breeze.

    I can only guess it was with redsnow or something because it had CYDIA on it which somehow disappeared or accidently deleted.
    The phone is currently using my sim card from tmobile, I have no problem downloading from istore but as you know most apps require something over 4.0

    Before you upgrade, use a program like iFaith to back up your SHSH blobs for 3.1.3. That's quite a rare firmware for a 3GS these days. :)

    If you're in the US use Unlock_Fusion off of eBay. Otherwise I would contact your carrier before using a shady website.

    Something to keep in mind:

    The 3GS takes a performance hit going from iOS 3.x to 4.x.

    It took another performance hit going from iOS 4.x to 4.3.x/5.x/6.x (mostly due to RAM).
