There was no news about the iOS 9.1 jailbreak and we’re pretty sure that nobody expected the Pangu team to finally release it for the public. Pangu, the hacker group, has released the iOS 9.1 jailbreak yesterday and it can be downloaded and installed on your iDevice right away. In order to install iOS 9.1 jailbreak you will need to download and install the jailbreak tool version 1.1.0 for Mac and 1.3.0 for Windows.
Pangu iOS 9.1 Jailbreak: Supported Devices
According to the changelog that Pangu has provided along with the iOS 9.1 jailbreak, it seems that this “cracked” version of the 9.1 update is only available for the 64bit devices. With other words, the new 9.1 jailbreak can be installed on devices such as: iPhone 5s, 6, 6s, 6 Plus, 6s Plus, iPad Pro, iPad Mini 2, Mini 3, Mini 4, iPad Air and Air 2.
Unfortunately, you will not be able to install the new iOS 9.1 jailbreak on 32bit devices such as iPhone 4S or the iPhone 5C, when it comes to iPod Touch, only the iPod Touch 6 will support the new jailbreak.
However, keep in mind that in order to install iOS 9.1 jailbreak on your iDevice, you will need to make sure that your device runs on 9.1 version, as the jailbreak doesn’t support iOS 9.2 or 9.2.1, Pangu has explained that they’ve used a kernel bug from Lokihardt to exploit iOS 9.1 and this bug is patched in the 9.2 version.
Unfortunately, Apple has stopped the signing of the 9.1 firmware months ago and if you’ve already upgraded to iOS 9.2 or later, you will not be able to downgrade. However, there are still a few users who have their iOS devices running on the iOS 9.1, so if you’re one of them, you can download the 9.1 jailbreak by Pangu right away and use it on your iOS device.
