How To Jailbreak Your iPhone 4, iPhone 3GS or iPhone 3G Using PwnageTool (iOS 4.1)

iPhone Dev Team has released PwnageTool 4.1.2 to allow iPhone users to create and update their iPhone with a custom pre-jailbroken iOS 4.1.

This guide will provide iPhone 4, iPhone 3GS and iPhone 3G users with step-by-step instructions to update and jailbreak their iPhone with iOS 4.1.

Some important points before we proceed:

  • Please note that jailbreaking your iPhone may void its warranty so proceed with caution.
  • Don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
  • Please ensure that your iPhone has enough charge.
  • This guide is only for iPhone 4, iPhone 3GS and iPhone 3G users.
  • PwnageTool is only supported on Mac OS X and is not supported on Microsoft Windows. Windows users should wait for Sn0wbreeze that is expected to be released shortly.
  • Users who want to Unlock their iPhone:
    • PwnageTool does not unlock your iPhone.
    • You can use Ultrasn0w to unlock your iPhone after you have successfully updated and jailbroken your iPhone  with iOS 4.1.
    • But there is a catch. Ultrasn0w 1.1-1 can only unlock the following basebands (you can check the baseband by going to Settings –> General –> About –> Modem Firmware):
      • iPhone 4 baseband – 01.59.00
      • iPhone 3G and iPhone 3GS basebands – 04.26.08, 05.11.07, 05.12.01 and 05.13.04
    • So if your iPhone is currently on iOS 4.0.2 or lower then PwnageTool 4.1.x will allow you to create a custom pre-jailbroken iOS 4.1 and preserve the baseband so that you can unlock your iPhone using Ultrasn0w 1.1-1.
    • If you accidentally upgraded your iPhone 4 with iOS 4.1 then its baseband would have got upgraded to 02.10.04. Unfortunately, 02.10.04 baseband shipped with iOS 4.1 for iPhone 4 cannot be unlocked nor can it be downgraded.
    • Similarly, if you accidentally upgraded your iPhone 3G or iPhone 3GS with iOS 4.1 then its baseband would have got upgraded to 05.14.02. Unfortunately, 05.14.02 baseband shipped with iOS 4.1 for iPhone 3GS or iPhone 3G cannot be unlocked nor can it be downgraded.
  • After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure. Also, remember to change the password of your jailbroken iPhone.
  • Please read the instructions carefully especially the ones highlighted in bold.

If you meet the requirements mentioned above then you can proceed with the step-by-step instructions to jailbreak your iPhone using PwnageTool.

Step 1: Download PwnageTool 4.1.2 from here or here and save it in a folder named “Pwnage” on your Mac desktop.

Step 2: You also need to download the iOS 4.1 firmware file:

iPhone 4 users download – iPhone3,1_4.1_8B117_Restore.ipsw

iPhone 3GS users download – iPhone2,1_4.1_8B117_Restore.ipsw

iPhone 3G users download – iPhone1,2_4.1_8B117_Restore.ipsw

Download the file using Firefox since Safari might auto extract it.

Step 3: Double click and launch the PwnageTool. This will create a PwnageTool icon that you can click and drag into the Pwnage folder.

Step 8: You will now be shown the Firmware bundle customization page. Click on ‘General‘ and press the blue arrow button to continue.

Deselect the option if you are with an official network carrier. Press the blue arrow to proceed. Here you can also enable the multitasking, custom Home screen wallpaper, battery percentage indicator that officially not supported in iOS 4.1 for iPhone 3G.

Step 10: In the ‘Cydia Settings‘ window, click on the ‘Download packages‘ tab and press ‘Refresh‘. This will display all the available packages. Select the ones you want (OpenSSH and OpenSSL) and then click on the blue arrow button

Step 11: Now click on the ‘Select Packages‘ tab. You will see the selected packages displayed here. Press ‘Select All‘ and click on the blue arrow button to continue.

Step 12: The ‘Custom Packages Settings‘ window will list package settings for your custom .ipsw. Click on the blue arrow button to move to the next step.

Step 13: Here you have the option to change logos for Boot and Recovery. You can choose the default images or click on browse to provide your own logos. Do note that the images need to be in grayscale/RGB with a maximum dimension of 320×480. Once selected, press the blue arrow button to continue.

Step 14: You are now ready to start the Pwnage process. Click on the Build button to select it and then click on the blue arrow to start the Pwnage process.
