FIRMWARE 3.1.3 IS NO LONGER THE NEWEST FIRMWARE SUPPORTED BY APPLE. WITH THE RELEASE OF IOS4.0, I WOULD ADVISE USERS OF THE iPHONE 3G AND THE iPOD TOUCH 2G TO UPDATE TO ios4 AND UPDATE USING THIS METHOD. IF YOU ARE USING AN iPHONE 3GS, iPHONE 2G, iPOD TOUCH 1G OR iPOD TOUCH 3G OR AN iPAD, DO NOT UPDATE TO ios4 AND USE THE METHOD BELOW INSTEAD.

Background (aimed at readers with little previous jailbreaking experience or those interested in a brief history of the iphone jailbreak. The method can be seen below).

Since I bought my first iphone, I have always had an interest in keeping it "jailbroken". This is a common practice among advanced users of iphones that allows you to have more control over what your phone can or cannot do. It is estimated that 10% of all iphones, ipod touches and ipads sold worldwide are jailbroken.

Contrary to what some people believe, jailbreaking your iphone is actually an extremely easy and safe process, providing you can follow some simple instructions. The release of the jailbreaking utility "spirit" around a month ago made the process simpler than it has been for many months, and allows anybody to jailbreak their iphone regardless of its firmware or model.

There are many advantages to having a jailbroken iphone. Jailbreaking allows for almost limitless customisation, from the ability to choose a new background to choosing an entire new theme to make your phone stand out from the crowd. Jailbreaking also allows the user to download apps from outside of apples official app store via a second "app store" named cydia. It is also possible to download apps for free that you would normally be expected to pay for from the app store.

important points

Jailbreaking your iphone does not unlock it. You will still need a compatible SIM card.

If you update your devices firmware, your device will go back to normal and the jailbreak is lost. Therefore to undo your jailbreak, simply update your devices firmware.

The method

0. Ensure your ipod touch or iphone is on firmware 3.1.3 (you can check this by going to settings>general>about on your device). If you have an ipad, you should be on firmware 3.2.

1. Download "spirit" from www.spiritjb.com. Versions are available for all common operating systems.

2. Install "spirit"

3. Connect the ipod/iphone/ipad you wish to jailbreak to your computer. Ensure no other apple mobile devices are connected.

4. Run spirit. The program is a simple box. It will show you the type of device connected and there will be a button labelled jailbreak. Click this button.

5. At this point, spirit will prompt you that your device has been jailbroken. A purple screen will be present on your device complete with a progress bar. Wait until this bar is full and your device reboots before disconnecting.

6. There will be an app named "cydia" on one of your iphone home-screens. Congratulations, your device is jailbroken.
