iFans forum member tw23 has uncovered a few more hidden “features” that one can enable on unjailbroken iOS 7. As previously noted by Joe, the first of these is a string that allows one to use the iPhone hardware switch to toggle orientation lock rather than use it as a mute switch.
Today, the same user posted a few more modifications including one to enable video rotation, and a couple that allow you to use number signal for Wi-Fi and cellular rather than the standard bars. Much like the previous one we posted about, these probably aren’t new to iOS 7 – but they’re cool nonetheless. To enable them, use the same instructions posted last time.
