Untethered iOS 4.3.4 Jailbreak Not Coming Soon!!!

Redsn0w has been updated to jailbreak iOS 4.3.4 but, a strange tweet has been published by i0n1c saying that the untethered jailbreak for iOS 4.3.4 may be impossible and users not expect an untether for iOS 4.3.4 anytime soon. Who haven’t upgraded to iOS 4.3.4 already to avoid doing it and install PDF Patcher 2 to fix the Safari’s PDF exploit…………

 

iPhone hacking expert Stefan Esser who goes by the Twitter handle i0n1c, credited for developing the untethered jailbreak used in tools like Redsn0w, PwnageTool and Sn0wbreeze for iOS 4.3.1, iOS 4.3.2 and iOS 4.3.3 has tweeted that it may not be possible to release an untethered jailbreak for iOS 4.3.4 anytime soon. In a series of tweets he has revealed that Apple has also fixed the untether exploit in iOS 4.3.4:

Don’t expect a iOS 4.3.4 untether anytime soon.

In a way it is nice to see that Apple instead of merely fixing vulns add more mitigation checks. But for jailbreakers this suxx.

The dynamic linker performs additional checks on the mach-o header to stop a class of attacks against the dynamic linker.

This is how Apple broke your hearts: ADD.W R3, R11, #0xFFFFFFFF – CMP R3, #9 – BHI get_out_of_here

It checks the demux_count in ndrv_setspec

Actually no. That code is the code that fixes the untether exploit.

Apple has also fixed the security vulnerability used by Comex in JailbreakMe 3.0 to jailbreak iPhone, iPad and iPod Touch. So the only option you have if you want to enjoy an untethered jailbreak would be to avoid upgrading to iOS 4.3.4 and ensure that you have taken a backup of the SHSH blobs via Cydia or using TinyUmbrella for iOS 4.3.3, so you can downgrade to an older jailbreakable iOS version if required.

Thanks
