Public iOS 9.1 update was released earlier this week, arriving with a bug fixes and a minor new features. However, it also patched up the Pangu iOS 9 – iOS 9.0.2 jailbreak. iOS 9.1 is not a major update by any means, unless you’re obsessed with emoji. iOS 9.1 comes with around 150 new emoji to play around with, including the middle finger emoji that many users have been looking forward to for some time.
There are also a handful of bug fixes and general performance improvements, including improvements for Live Photos on the iPhone 6s, as well as improvements to Live Photos sharing on older iOS devices
Pangu team work hard for update theirs Pangu 9 tool for Jailbreak iOS 9.1. Apple patched up the iOS 9 jailbreak in the fourth beta of iOS 9.1, which is why Pangu released the jailbreak when they did. We expected the iOS 9 jailbreak to arrive once iOS 9.1 was released to prevent Apple from patching up the exploits in iOS 9.1 update. However, since that has happened, Pangu team decided to release the iOS 9 jailbreak earlier than usual.
At this point, it’s hard to say when an iOS 9.1 jailbreak download will available. It could be soon, or it may never come and we’d have to wait for an iOS 9.3 jailbreak or another like iOS 8, an iOS 8.1 jailbreak was released quickly, but there wasn’t another jailbreak tool until a couple months after iOS 8.3 JB was released.
if you updated to iOS 9.1, you can still downgrade to iOS 9.0.2 for the time being while Apple is still signing the iOS 9.0.2 update. The downgrade should be available for the next week, but Apple has been keep signing older versions for a couple of weeks before stop signing to older versions.
