I love my phablet. I love it. However, there's just times where I just need a smaller device. Class, for example, if I want to send a message discreetly. However I want to update to iOS 8 but I'm still deciding; 8.1 or 8.1.1? Apparently, the speed increase is not good, it's just a little bump and is virtually useless. And I might want to jailbreak. I love f.lux, and it's amazing. I prefer to have the yellow filter all day, but there isn't a version for android. So taking this into consideration, which firmware should I use? 8.1/8.1.1?
