Thinking about downgrading to 7.1.2 again.. thoughts? I've been using iOS 8 for a week and now realized that I miss my JB, but on the other hand I kind of like being back on stock for now because of the features Apple has added on. Should I update to 7.1.2. or stay on 8? What if I decide I want to go back to 8? Would I be able to do that?
