Looks like our old friend George Hots (geohotz) is up to a lot of good!  The 24kpwn exploit present in the iPod Touch 2G is still present in the iPhone 3GS. Check out his full blog post here!  Looks like an iPhone 3GS jailbreak is right around the corner.  And from what I can see, the unlock as well.  Please read George’s blog as it has some information you all will want to know about being able to jailbreak your iPhone 3GS.
