Now press and hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.

After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.

    This method won't work on an iPhone 3GS running iOS4 and the new bootrom. After preparing the custom firmware and restoring it you'll get the 1604 error. You can verify it at the Dev-Team' blog (

    “If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.01”
