So if you are a Mac user, you can download PwnageTool 4.01 to upgrade the firmware of your iPhone or iPod Touch to iOS 4.0 without changing the baseband. After you had successfully jailbroken your iPhone, you can use ultrasn0w 0.93 to unlock it so that you can use a sim of your choice.

Procedure to Jailbreak iPhone 3GS/3G and iPod Touch 2G With PwnageTool 4.01

  • Get the latest iTunes 9.2 and take a backup of all your important data.

Turn off your iPhone and then press the following keys in sequence – Hold down the home button for 5 seconds and then hold the Home and Power buttons for 10 seconds.

  • Now browse and select the custom IPSW file and click on “Open”.
