Yup.
So now, they jailbroke 3.1.3, 3.2, and 4.0.
And they've released none of them. That's got to piss a lot of people off, but I completely see their point as to why they haven't released it to the public yet. I'd rather wait and have 4.0 jailbroken then have the betas jailbroken and get screwed by Apple when the gold master is released.
