by casey on April 4, 2011

As we have already told you the good news. iPhone Dev Team has finally released untethered iOS 4.3.1 jailbreak for iPhone, iPad, iPod Touch and Apple TV 2G. They have released two tools; redsn0w 0.9.6 RC9 and PwnageTool 4.3 for this purpose. The jailbreak solution is available for the devices which includes iPhone 4, iPhone 3GS, iPod Touch 3G, iPod Touch 4G, iPad 1.

NOTE it is NOT compatible with iPad 2 device. iPad 2 users have to wait a little longer to get untethered 4.3.1 JB.

Remember the exploit used by iPhone Dev Team behind Redsn0w 0.9.6 RC9 is originally developed byStefan Esser who is a security expert. Previously he handed over his exploit to the iPhone Dev Team. So a great thanks to Stefan Esser.

Although iOS 4.3.1 Jailbreak was already possible but that was TETHERED usingSn0wbreeze 2.4 andPwngeTool. Now this time they have released the untethered version.

    My phone crashed during the tethered 4.3.1 update and I was unable to restore it all weekend.

    I tried this jailbreak and it’s still asking me to connect to iTunes.

    Does anyone have any solutions?

    • Solidator

      Give a complete restore via iTunes then go head with the untethered Jb

    I’m new at this… I installed everything and it was a success. Cydia opened up and everything. The only problem was that I had no contacts, text messaging, calls, nothing at all. Is there something that I am supposed to do to get those back on my phone or are they supposed to be there from the get go? Help please.nnThanks guys

      Oh, sorry to say, but jailbreaking means wiping clear your phone. I hope you got everything backed up on your computer or else you have to start from scratch

  • Firearmspro

    When I download the firmware, I don’t see a .ipsw file anywhere in the folder??? I may just be an idiot, but I have tried on 3 different computers and I never get a .ipsw file that RedSn0w will recognize. Any ideas….

    I am receiving an error message shortly after my iphone 3GS begins the reboot, post entering DFU mode. I have tried numerous times with the same error resulting. I have even restored my phone and reinstalled redsn0w. can anyone share any insight on the issue i am experiencing? Thanks in advance for your time.
