Update: PwnageTool 2.0.1 (still Mac only) has been released with bug fixes. This PwnageTool 2.0 Guide remains applicable.
Note: PwnageTool 2.0 is for Mac only at this time. You also cannot upgrade from firmware versions older than 1.1.4. I suggest you use my other guide if you need to upgrade your iPhone to 1.1.4 first.
