I got an iPhone 6S Plus a year ago, and managed to keep it jailbroken as I upgraded from iOS 9 to 10. With the latest yalu hack I was able to upgrade to 10.2, just hours before Apple closed the signing window. Then a few days ago, disaster struck: I dropped my phone and shattered the screen. Fortunately I had insurance, so a couple of days later I got a replacement phone delivered. I was sure it would be loaded with 10.2.1 and my days of jailbreaking joy were over. To my surprise, it was loaded with 10.1.1, so I'm still living the jailbroken life.
