Earlier today we posted a tutorial on how to jailbreak an iPhone 3GS running iOS 4 with an unofficial build of PwnageTool. Now, the Dev-Team has just release its official build of PwnageTool, read the blog post here.
PwnageTool 4 works on the iPhone 3G / 3GS and iPod Touch 2G. iPhone 2G, iPod Touch and iPod Touch 3G are not supported. The process of creating a custom firmware is the same we described this morning.
Enjoy your jailbroken iOS 4, folks.
