2.2.1 Breaks 3g Unlock, Does Not Break Jailbreak Method

MuscleNerd of iphone-dev has been updating us via his twitter account with some info about firmware 2.2.1 which was released yesterday.
2.2.1 does not break the dev team's methods of jailbreak.
2.2.1 breaks the 3g software unlock
2.2.1 does not break iPhone 2G unlock since the 2G baseband is not updated.
(it hasn't been updated for 8 months)
Don't Upgrade yet though . . .
For anyone that wants/needs to unlock the iPhone 3g do not update to 2.2.1 until the dev team releases a method (i.e. PwnageTool) for a 2.2.1 jailbreak/upgrade. If you upgrade to 2.2.1 your baseband will be upgraded and it is unclear if/when you will be able to unlock.
