The iphone-dev team has just released PwnageTool 2.0.2 which jailbreaks the new 2.0.1 firmware.  You can update from within the software if you have the last version installed already. If you do not, it is also available via direct download for use with Finder.

This new PwnageTool comes complete with Installer4 beta as well as the latest version of Cydia with it’s new features.

Installer4 Repository: We’re hard at work with preparing the repo packages for the new Installer. A few packages are already present in community sources and we’ll be adding more over the next several hours. There will no longer be a “Planet-iPhones Mods” category in Installer. Instead look for the “Mods” category and the “Themes” categories.

Developers: We will host your theme or app in Cydia and Installer! Use this form to submit your package.
