Hi. I am currently jailbroken to 9.0.2 (iphone 6s) which is very stable. want to upgrade to ios 10, 11, or 12 whichever stable and possible. Want to ask if it's possible? I'm happy with my 9.0.2 with all the cydia apps, etc. but I need a higher version of IOS to use my apple watch. Thank you for the help.
