    Yes. You can upgrade to 3.1.3 (best iOS for the 3G, 4.x.x make the 3G act like a snail).

    Here's a guide on how to jailbreak 3.1.3 --> <--Windows Route


    If you have a Mac and really want to go 4.0-4.1 you can use PwnageTool. PwnageTool preserves your baseband so you can unlock on the newer/newest iOS.
