Yesterday, iOS 6.0 was released to the public available for the iPhone 4s, 4, 3Gs, iPod Touch 4G, and iPad 2, 3. So far, only the iPhone 4, iPhone 3GS, and iPod Touch got tethered jailbreak. Many jailbreakers why only the above devices work and when an untethered iOS 6 jailbreak would come. Folks over Jailbreaknation have give the answers for that.
Only one day later it was reported that over 15% of all devices are now running the updated software.
"An exploit was found a while ago called limera1n which could only get fixed with a hardware upgrade. This means all devices with the a4 chip (iPhone 3GS, iPhone 4, and iPod Touch) could be jailbroken forever. This exploit was not untethered therefore new software versions will require to exploits to be untethered."
"We have no idea when a new exploit will be found but there are a few things we can tell you. There is a great certainty that when an exploit is found it will work for are devices untethered. Last year it took months, but it could take as short as a quick find in a few days."
That sounds really good for A4 users. The good news is, we know that the main hacker team are still working on the jailbreak. We will keep you updated.
