Double-Press: When the phone is locked or in sleep mode, a double-press of the Home button wakes your device and brings up both the iPod controls and a shortcut for the Camera app. In active use, it brings up the multitasking bar, showcasing your active apps.

Headphone Jack

The new iPhone has a standard 3.5mm audio jack, located on the bottom of the device. Apple includes a set of white EarPods that allow you to listen to audio and speak on a call, but you can also use any pair of third-party headphones instead.

Microphone

One of the iPhone 5's three microphones is located on the bottom left of the device. (The other two, which are designed to filter out noise, are located on the front and back.) Unless you're using an external microphone, you'll speak into these when making calls, recording voice memos, talking to Siri, and more.
