It must be prohibited, because surely someone would have developed a non-JB version of what SBSettings does. Honestly, I have ZERO need to jailbreak my phone EXCEPT for this ONE extremely handy app. It is WAY too many screen taps to turn WIFI off and BT on every time I leave the building, and vice versa. SBSettings let's me do this with a swipe and 2 taps. So I jailbreak. Ridiculous.
