The iPhoneDev Team have released version 2.0.1 of their brand new PwnageTool that supports the 2.0 firmware. I will post the bug fixes from their blog.

• “It auto-finds the bl39 and bl46 files better, if they’re on your computer
• It creates the ~/Library/iTunes/Device Support/ folder if not present, which should help with some 1600 errors people have been having.
• Many people have reported the PwnageTool not starting up at all (the icon never stops bouncing). This issue should be resolved now.
• The Sparkle AppCast URL is fixed in this version, so automatic updates should work for future releases.

Because of the AppCast URL fix, we recommend that everyone who downloaded PwnageTool 2.0 get this version, if they want to stay up to date automatically.”

The tool can be downloaded from here or here. The DevTeam said that if you download from mirror sites, be sure the SHA1 of the file is 10b6c7dc22286e7b70c3d5a92cda7d117426fda9.

Note: If you have successfully pwned your phone using the first Pwnage 2.0, there is no need to pwn again with 2.0.1.
