iPhone 5 takes dictation.
Instead of typing an email, tap the microphone icon on the keyboard and start talking. Tap Done, and your words will appear as text. Use dictation to write messages, take notes, update your Facebook status, tweet, and more.
Switch directions in Panorama.
In panorama mode, you can easily shoot from left to right or right to left. Just tap the arrow to switch the direction.
Tweet it. Post it.
Sign in once under Settings, and you can tweet or update your Facebook status directly from Safari, Photos, Camera, and Maps. Or ask Siri to do it for you.
Customize your keyboard.
Create your own personal dictionary, including shortcuts for each word. So your keyboard not only autocorrects, it knows exactly what you want to say as you type. In Settings, tap General > Keyboard > Add New Shortcut. From there you can add new phrases and assign optional shortcuts to them.
