How to turn off the lock rotation on a iPhone 5?
Assuming you have iOS 7, just swipe up from the bottom and you should find a toggle screen with orientation lock on it
IOS 7 swip upward from the VERY bottom of the screen to get the control center and you will see 5 buttons. One looks like an airplane, a Wi-Fi signal indicator, a Bluetooth 'B' symbol and to the right a button that looks like a arrow in the shape of a circle. When the lock appears the screen lock is ON.
