iPhone OS 3.0.1 jailbreak, unlock and tether-able

Apple's freshly-released iPhone OS 3.0.1 update fixes a bug that allows arbitrary code execution via SMS messages. The bug, exposed by Charlie Miller and Collin Mulliner at last week's Blackhat conference is particularly nasty because it allows a hacker to root an iPhone via a series of text messages -- which are push, and not optional.

The good news is that 3.0.1 doesn't disable tethering and you can still jailbreak and unlock an iPhone running the new software. Needless to say, all iPhones should be updated to the 3.0.1 software (available via iTunes) as soon as possible now that the hack is in the wild.
