How to Jailbreak iPhone 3GS on iOS 4.1 using PwnageTool ( PC / MAC guide )

In the following guide you will learn how to Jailbreak iOS 4.1 on your iPhone 3GS. Please read the following lines with the greatest attention ever, as this is not the official jailbreak tool that we are all expecting. This process works only for an iPhone 3GS with an old bootrom. Also, please note that this version of PwnageTool will not hacktivate your iPhone 3GS. For that you will need the original SIM or an SIM phonebook. After following our guide to jailbreak iOS 4.1 on the iPhone 3GS, you will also be able to unlock it. A guide for that will soon be available after the break.

Now let’s explain a bit how we will jailbreak the iOS 4.1 on the iPhone 3GS: we will first backup your data, install PwnageTool, create a custom firmware and then restore it. It will be a bumpy ride, but it’s worth.

iOS 4.1 got Pwned

Jailbreak iOS 4.1 on iPhone 3GS with PwangeTool
  1. Download and install the latest version of iTunes.

  3. Download PwnageTool and then the iOS 4.1 firmware, for the iPhone 3GS.

  4. On your PC / MAC, start PwnageTool and Choose the “Expert Mode”, at the top of the screen.

  5. Select the iPhone 3GS and then click on the blue arrow, like bellow:

  7. On the next screen, you will be asked: “Do you have an iPhone contract that would activate normally through iTunes?”. Choose No. This will make the iPhone 3GS to keep its baseband.

  8. Now the custom firmware is being created. PwnageTool will ask you to authenticate your account on Mac. Ignore this and go to your folder downloaded on step 3, you should find the “iOS4.1Jailbreaker”. Install it, go back to the PwnageTool password prompt and then enter your password. You should see an “iHAZ success” message.

  9. Now we will restore the firmware. Start iTunes and click on your phone icon, in the sidebar. Press and hold the left “ALT” button ( “Shift” button if you are using a PC ) and then click on the “Restore” button. Now release ALT / Shift.

  10. iTunes will ask of you to select the custom 4.1 firmware. Browse to it, select it and the press “Open”.

  11. Wait a while until the process is complete. This will be ended with a phone restart. If you will receive a 1004 error, this is OK. Just ignore it.

  12. The last step is to get the iPhone 3GS out from recovery. Download TinyUmbrella ( PC / MAC ) and install it. Run the program and simply press the “Kick Device Out of Recovery” button. Your device will now restart in the pure jailbroken iOS 4.1 form.

Note: If you go to Cydia and you have a white screen, add to the rep.

Note2: If Safary crashes, add repository and install Safarifix.

Note3: To get all of your data back into your jailbroken iPhone 3GS, go to iTunes and restore the backup you did at the start of this guide.
