I might jailbreak my 3GS just to see what's out there. I'm going to keep my iPhone 4 virgin though :)

I'm pretty sure that if you've done updates to your 3gs and never jailbroke it before you can't jailbreak it anymore. If I'm wrong and you know they way to do it please let me know. I've been searching and searching and can't seem to find a way.
