iOS 4.3.4 Available for Download, iPad 2 Jailbreakers should STAY AWAY!

Apple has released iOS 4.3.4 to fix the PDF security exploit used by JailbreakMe 3.0 to jailbreak iPad 2 on iOS 4.3.3. iPad 2 users who rely on a jailbreak are outright warned to stay away from the iOS 4.3.4 firmware update.

iOS 4.3.4 is released for iPhone 4 (GSM), iPhone 3GS, iPad (1st Gen), iPad 2, iPod Touch 4G, and iPod Touch 3G. Except for iPad 2, this update will not result in loss of jailbreak. This is because the rest of the devices had a bootrom exploit, which is being used in Redsn0w, Sn0wbreeze, and PwnageTool to gain root access.


The previous release, iOS 4.3.3, fixed some issues relating to iPhone location data storage. There has been a long gap between the two releases, bringing up speculation that Apple may eventually go for iOS 5 release this fall and may skip any iOS 4.3.x updates. However, the release of JailbreakMe 3.0 has changed this, and Apple has pushed iOS 4.3.4 with only one security update – to close the PDF exploit used by the iPad 2 userland jailbreak.

Using PDF exploits in Mobile Safari browser to jailbreak iOS firmware is not new. Previously, we have seen JailbreakMe 2.0, a browser based jailbreak for iOS 4.0/iOS 4.0.1 and iPad 3.2.1. You can make JailbreakMe work for you by simply navigating to from your Safari Browser and following the instructions on that page.

Here are the direct download links of iOS 4.3.4. After downloading the IPSW, open iTunes and click on ‘Restore’ button while pressing SHIFT key (left OPTION key on Mac). Let iTunes prompt you to select the firmware and there after restore your device.
