Apple really wants to put a lid on jailbreaks, they have now stopped signing iOS 9.2.1.

This means that the lowest version of iOS you can restore to is 9.3, so be careful with what you install or do on your device if you’re jailbroken as this could leave you without one.

We can only hope a jailbreak for 9.3 and 9.3.1 is released soon.
