iOS 4.3.3 was released an hour ago and comex is already trying to check it to see if the exploit for untethered jailbreak from iOS 4.3.1 is still available. To our joy, the exploit still exists and can be used to jailbreak. For now, there is no jailbreak program 100% compatible with iOS 4.3.3 because there are no special bundles. I managed to do a tethered jailbreak on iOS 4.3.3 using the latest version of redsn0w and an ipsw 4.3.2, so we will have to wait for new untethered jailbreak solutions. I assume that they will be available soon considering that only a few minor changes will be needed.
UPDATED: You have here a tutorial for tethered jailbreak.
