If you’re sittin’ there in iTunes with your finger hovering over the “Update” button, anxiously awaiting word of an untethered jailbreak for the just-released iOS 4.3.3: it’s go time.
In fact, it was go time almost immediately after the update went out; turns out, the exploit that the iPhone Dev Team has been using for the last two builds of iOS is still wide open here, so they just had to tweak some checksums to give the redsn0w jailbreaking tool the go ahead to patch iOS 4.3.3 files. You’ll need to download the latest copy, but it should all be smooth sailing past that.
