It is not long since the iOS 4 has been released (a Gold Master Release was made available for developers only yesterday), and it has already been Jailbroken for the iPhone 3GS (video below). Still, this is not a ‘touched up’ iOS 4 Jailbreak, so it has not been highly recommended for a non-expert iPhone user. Jailbreak at your own discretion. iPhone HD not out yet, so no Jailbreak for it yet.
