Jailbreaking Process

In April 2011 the iPhone Dev-Team released untethered updates to all the major jailbreak apps for iOS 4.3.1. Here is how to jailbreak your iPhone with this OS for each app:

Pwnage Tools 4.3 – Jailbreak iOS 4.3.3 (tethered)

Pwnage Tools 4.3 is the most recent version of Mac iOS jailbreak software. Here is a step-by-step guide to installing Pwnage Tools 4.3:

1. Step Follow this link to Download PwnageTool 4.3 for Macs.

2. Step Download the proper iOS 4.3.3 firmware for your mobile device. Once it has been downloaded you should Move the program files to the device’s desktop.

3. StepSelect Pwnage Tool and choose “Expert mode.” Select your particular device.

4. Step Browse the app for the iOS 4.3.3 firmware for your own device.

5. Step Select the “Build” option to begin making a customized 4.3.1 firmware file.

6. Step The PwnageTool 4.3 app will then create the customized .ipsw file for your device.

7. Step Follow these steps to go into DFU mode: hold the “Power” and “Home” buttons down for 10 seconds; let go of the “Power” button, but keep holding down the “Home” button for another 10 seconds; the device should be in the DFU mode.

8. Step Start the iTunes app on your device and select your particular iOS device icon. Press down and hold the left “alt” (option) button if you are on Mac, or press down the left “Shift” button if you use a Windows keyboard. Click “Restore” in iTunes and then release the button.

Don’t use the “update” or the “check for update” options. This makes iTunes request that you select the location for the customized firmware 4.3.3 file. You should select the necessary custom .ipsw file which you had created in the precious step and click “Open.”

9. Step After this, iTunes will basically do the rest in an automated process. The user has to exercise some patience and not interfere with the device, even if it looks like it might be “stuck.” Wait until iTunes has installed the new 4.3.3 firmware on the device.

You will know it is at that point when the progress bar reaches 100%. At this point the iOS device is jailbroken at the iOS 4.3.3 level.
For an illustrated guide to this process, watch the video above.

Why Jailbreak? Why Not?

“Jailbreaking” is the process by which a user can get full, or root, access to all the features of the Apple iOS operating system on its mobile devices. All Apple devices, apart from the new iPad 2, can be jailbroken right now, including the iPhone 3GS, the iPhone 4, the first-generation iPad, and the iPod Touch in 3 or 4G. The most recent untethered jailbreak is for the newest iOS 4.3.1 firmware.

Apple is infamous for its control of how users access and utilize their products. For some, this trait is a good thing, providing users a safe and stable platform with exceptional features and performance. Others dislike being limited to Apple’s App Store offerings and not being able to use all of their device’s features in the ways they like. By jailbreaking a phone the user can access third party apps, programs and themes which aren’t available through the App Store, among other advantages. Some negatives of jailbreaking are that it voids the warranty and causes more instability in the device.

Jailbreaking iOS 4.3 Untethered

Hackers all over the world can’t resist a new challenge, and cracking Apple’s iOS was no different—in fact, it is more challenging in many ways, as Apple’s software is so intrinsically different from Windows and is used by a much smaller segment of the market, except when it comes to mobile devices. A hacker group called the iPhone Dev-Team was the first to develop an iPhone jailbreak app called Pwnage Tool in 2008. This app is still in use in the most recent iOS jailbreaking techniques for the iOS version 4.3, as well as other apps such as RedSn0w and Sn0wbreeze.

Tethered vs. Untethered

There are two forms of jailbreaking: tethered and untethered. In tethered jailbreaking the device has to be connected to a computer every time it is booted into the jailbroken state. This can be inconvenient for most users, who use their devices on the go. A tethered jailbreak is when the device can be powered off, then powered back up again and rebooted without being connected to a computer. With either method the jailbreak can be reversed by retrieving the original settings through iTunes.

Jailbreaking an Apple device has its advantages and disadvantages. By utilizing the steps and information given in this piece the user acknowledges that they do indeed void Apple’s factory warranty and accept any consequences. In the same token, there is much to be gained by opening these innovative and useful devices to third parties and customization by their users.
