There's nothing wrong with Jailbreaking. I jailbroken my iPhone countless times since I like to update to the new iOS when a update hits but I don't update if there's no jailbreak available. As I recall iOS 9.2-9.3 still don't have a jailbreak so I'm on 9.0.2 still. If you're on 9-9.1 or even less than that then feel free to do it. It's honestly a much better experience. If you need help, their are a buttload of tutorials on the interwebs and YouTube.
