This is fun. It's like a game of cat and mouse between Apple firmware and the jailbreaking community, Apple launches an update and the iPhone-dev team works feverishly to jailbreak said update. This time, they are said to be putting the finishing touches on PwnageTool 2.0.2 which will be able to jailbreak the "snappier" 2.0.1.
Excited much? Well, there still won't be Installer.app because Installer 4 isn't ready for the primetime yet but a new version of Cydia will be there so you can still get some apps. There still is a lot of catching up to do on developing jailbroken apps and it still won't unlock the iPhone 3G, but all in due time. We'll follow up with a link to PwnageTool 2.0.2 when it is released.
