Patches from iOS 4.3.4 as Jailbreak Exploit… is damage?

Monday, July 18th 2011. | Gadget News

On Friday, Apple released a minor update to iOS, version 4.3.4. The update patched the famous PDF exploit used by JailbreakMe 3.0, which allowed users to jailbreak any iDevice (including iPad 2) through a website. Some bloggers purported the latest update would also quell future jailbreaks- which anyone following the cat-and-mouse game between Apple and iOS hackers should know would turn out false. Well, it did, and less than 12 hours after the release of 4.3.4, a jailbreak was released by RedmondPie.

The jailbreak comes either in the form of a custom 4.3.4 bundle to be used with PwnageTool or simply by using the newly updated redsn0w tool. It is a tethered jailbreak, meaning if your device is restarted, the jailbreak must be reinstalled. RedmondPie’s jailbreak does not work on iPad 2.

While Apple has made pretty clear their opposition of jailbreaking, it is important to emphasize that 4.3.4 fixes a critical security hole– regardless of its use as a jailbreak exploit, a patch was necessary. Apple has just pushed out iOS 4.3.4 for the iPhone, iPad and the iPod touch. And thankfully, we have cooked custom PwnageTool bundles which allows you to jailbreak any device (except for iPad 2) running iOS 4.3.4, and at the same time preserve your baseband for an Ultrasn0w
We have tested and can 100% confirm that they are working. Keep in mind that the jailbreak is tethered for now, in other words, if your device loses power or restarts then you would have to boot it into the jailbroken state again. No matter how annoying it may sound, but its better than having no jailbreak at all.
The neat thing about PwnageTool is that it allows you to preserve your iPhone’s baseband, which aids in unlocking your iPhone later on using Ultrasn0w unlock. In this guide we’ll show you how you can jailbreak your iPhone on iOS 4.2.4, preserve your baseband and unlock it with Ultrasn0w, let’s get to it!

Things you’ll need:

PwnageTool 4.3.3
    iOS 4.3.4 firmware
    iTunes 10.3.1
    Mac OS X
    PwnageTool bundles for iOS 4.3.4
    tetheredboot utility

Important note:

There is no unlock for iOS 4.3.4’s baseband, hence do not hit the update button in iTunes if you rely on a carrier unlock.
Your baseband will be preserved during the whole process.
This jailbreak is semi-tethered.
Hacktivation is fully supported
