It won't work.
Apple stopped signing all firmwares lower than their current, official 3.1.2.
If he tries, it will freeze and lol up during the installation and force him to upgrade to 3.1.2 officially, destroying his unlock.
However, if he jailbreaks his current 2.2.1, HYPOTHETICALLY, and then got hold of a Pwnage Tool created ipsw for 3.1.2, he SHOULD be able to upgrade to the CURRENT 3.1.2, AND retain his unlock simply by downloading ultrasn0w through cydia.
Can any experts confirm this theory?
