iPhone 6s Plus iOS 9.3.1 Update: 10 Things You Need to Know

iOS 9.3.1 Jailbreak Release MIA

If you want to jailbreak the iPhone 6s Plus to run Cydia apps and tweaks you will need to stick with iOS 9.1 or lower. There is no iOS 9.3 jailbreak at this time and no iOS 9.3.1 jailbreak either. 

We've heard chatter and many rumors of a iOS 9.2 jailbreak and lately of a iOS 9.3 jailbreak, but it is still not available and there is no known date. 

You cannot downgrade to a jailbreak-able version on the iPhone 6s Plus, so you should stick with what you are on or you should decide if the new features are worth giving up your jailbreak for.
