Last week Apple released the latest firmware 2.2 for the iPhone and iPod Touch. Thanks to the team at iPhone-dev, the jailbreaking app ““ Pwnage Tool and QuickPwn were released days after the firmware release. If you are looking for a simple guide to easily jailbreak your 3G iPhone, here it is.

Note:

1) The tutorial I am going through below is only for the 3G iPhone using the Pwnage tool. This is meant for iPhone users who want to preserve their baseband firmware in the hope of unlocking it in the future. For those who already have an unlocked iPhone or who don’t care about unlocking their iPhone, a quicker and faster method is to use the QuickPwn.

2) This method does not work on the latest generation of Macbooks. If you are using the late 2008 model aluminum MacBook, MacBook Pro, or MacBook Air, you will not be able to jailbreak your iPhone.

Disclaimer:

I have tested this tutorial on my Macbook and iPhone and it works well. Your results may vary.

Jailbreaking Your iPhone (Preparation)

Download the Pwnage Tool (torrent file) and iPhone 3G firmware 2.2.

Starting the Jailbreaking Process

Open your Pwnage Tool. At the top menu, select the Expert mode.

Select the iPhone 3G image.

The tool will now scan your computer for the firmware. Select the one that you have just downloaded.

The next page is where you need to pay a little more attention. When you are in the “General” tab there are a few things you must take care of. Here you will decide your partition size – 530 MB should be good. Next, if you are using your iPhone on an official carrier (AT&T, O2, Rogers, etc.) uncheck “Activate the phone”. Lastly, check “Disable partition wipe-out”. Hit the arrow button to continue.

Click on the ‘Build’ button to start building the custom firmware. It will first prompt you for the location to save the custom firmware. The whole firmware building process will take about 5-10 minutes.

Once it is done, it will instruct you to turn your iPhone to DFU mode. Follow the instructions :

• first, switch off your iPhone
• hold the power and home button for 10 seconds
• release the power button and continue to hold the home button for another 10 seconds

If everything went correctly, your iPhone should now be in DFU mode.

Back to your iTunes, press the Alt/Option button and click ‘Restore’. Select the custom firmware that you have just saved. Sit back or go for your coffee break.

Your iPhone should now be jailbroken.
