How To Jailbreak iPhone 3GS on iOS 4.0.1 Using PwnageTool Bundles[Mac]

PwnageTool bundle to jailbreak iOS 4.0.1 on iPhone 3GS has been released. You can use this bundle with existing version of PwnageTool to create custom firmware files which are jailbroken and hacktivated for iPhone 3GS. The best thing about this bundle is that it supports both the ultrasn0w unlock and hacktivation. But as always, this bundle is meant for iPhone 3GS with old bootrom only. Those of you who are with new bootrom will have to wait for Comex's new Spirit like jailbreak tool which should be released real soon.
