Apple’s iPhone sports a fairly impressive virtual keyboard that does its best to predict what you are typing. It even automatically activates the Shift key at the beginning of a sentence, and shuts it back off after you type the first letter. By default, however, entering a string of all uppercase letters, like CAPS LOCK, is kind of a pain because you have to tap the Shift key before each letter.The iPhone does include a Caps Lock feature -- the trick is finding it so you can turn it on. Here’s how: Tap Settings Tap General Tap Keyboard Tap the Enable Caps Lock slider The Caps Lock slider is like a toggle switch. Tapping it once enables the feature, tapping it a second time shuts it back off.Using the Caps Lock is really simple: Quickly tap the Shift key twice. Instead of the usual glowing arrow that tells you your next letter will be upper case, the whole Shift key turns blue. Tapping the Shift key again turns Caps Lock back off.
