in my experience of fail, NEVER be left without a JB iPhone, even if it means selling it later to lag the gap- iPhone 6 premature leap for me was ridiculously painful,
i dont mind buying stock knowing it will get it eventually most likely, but i need a phone in rotation that is to my liking otherwise the walled garden gets me in virtual padded walls mentality
I lucked out buyin 9.7 pro the weekend that pangu unexpectedly dropped for 9.3.3, took a few more days to iron out for pro's to work but amazing
and bought SE like 3 or 4 weeks before pangu as well, but as secondary to my jailbrokne 6s plus but was daily driving on iOS 10 beta, until 9.3.3 jb came along
so crazy to have been doing this stuff for nearly a decade (being a consumer jailbreaker, hell bent on the perfect custom UX apple won't provide me-- dont pirate piss though as a side note cant say i didnt dabble early on in the jailbreak days)
