Locked Home Screen. One meaning of the term locked iPhone refers to an iPhone with a locked home screen. All iPhones have a lock feature that allows a user to lock his home screen when the phone is not in use to prevent him from accidentally activating the touch screen while the phone is in his pocket.
The home screen on the iPhone and iPod touch can't rotate (though it can on the iPad) and some apps are designed to only work in one orientation. If you turn your device and the screen doesn't reorient, check to see whether the orientation lock is present in the top corner.f you set Use Side Switch to: Lock Rotation, then that button is the only way to lock and unlock the screen. However, if you set that to be the Mute button, use the steps described above for the iPhone/iPod touch to access the screen rotation lock.
