Apple has released iOS 4.3.4 to block the exploit used by comex to jailbreak devices on iOS 4.3.3 and this update fixes security vulnerability associated with viewing malicious PDF files. You can download iOS 4.3.4 firmware for iPhone 4, iPhone 3GS, iPad 2, iPad 1 and iPod Touch 4G / 3G, which is supposed to fix PDF exploit used in JailbreakMe 3.0 to jailbreak iPad 2……………..

Apple released the iOS 4.3.4 update for the iPhone 3GS, both the GSM and CDMA versions of the iPhone 4, both generations of the iPad and the third and fourth generation iPod touch and also iOS 4.2.9 for Verizon iPhone to fix the vulnerability that was used by Comex in JailbreakMe 3.0. Comex had released JailbreakMe 3.0, one of the easiest solutions to jailbreak iPhone, iPad and iPod Touch early last week, which uses a userland exploit to jailbreak and install Cydia on an iOS device using mobile Safari. Security experts had raised concerns that the vulnerability in iOS could be exploited in a similar way by malicious websites to install malware. Apple had acknowledged the issue earlier in the week and announced that it will release a patch to fix the vulnerability shortly. Products compatible with this software update:


  1. iPhone 4 (GSM model)
  2. iPhone 3GS
  3. iPad 2
  4. iPad
  5. iPod touch (4th generation)
  6. iPod touch (3rd generation)


Comex expected Apple to release an iOS software update (iOS 4.3.4) to fix the vulnerability used in JailbreakMe 3.0 and has advised users to take a backup of SHSH blobs. You can use TinyUmbrella for iOS 4.3.3 or iOS 4.2.8 to take a backup of your SHSH blobs so that you can downgrade to the older version of iOS if required. Jailbreakers and iPhone unlockers should also avoid upgrading to iOS 4.3.4 if it is released, until the jailbreak community does not release the latest tools for iOS 4.3.4. If you don’t want to upgrade to iOS 4.3.4, but don’t want to be exposed to the security vulnerability then you can install PDF Patcher 2 on Cydia to fix the vulnerability associated with viewing malicious PDF files. If you don’t care about jailbreaking or unlocking your iPhone then you can update your iPhone with iOS 4.3.4 or iOS 4.2.9 via iTunes.
