Are people still jailbreaking? Wow.
Well, a lot of us aren't since there isn't an iOS 6 JB for A5 and newer chips. However, when one is released, I will definitely JB my 5 and mini. I don't go crazy, and I don't steal apps, but there are a number of jailbreak tweaks that really improve the experience of the phone, and frankly I like theming my icons.
While I'll take my stock iPhone 5 over my formerly jailbroken iPhone 4S, I do miss a few of the tweaks and themes. I really miss NC Settings and the tweak that allows you to swipe over the keyboard to act as cursor placement.
