If you're waiting for a jailbreak before updating to iOS 4.3.3, you might be happy to know that redsn0w 0.9.6b15 will do the trick. This is the same untethered jailbreak that we've seen since iOS 4.3.1, which we don't mind at all. Just download the latest version of redsn0w, and go for it. This'll work with iPhone, iPod touch, and first-gen iPad. iPad 2 is still being fairly unreasonable about allowing itself to be jailbroken for the time being.
