Airplane Mode: What is it?!

While on vacation, I took a plane. And I thought, why not make a quick explanation on Airplane Mode? For those who don't know, Airplane Mode (accessible from your Settings) is a mode that disables all wireless functions on your phone. You can optionally turn on WiFi manually after disabling it. When do you use it? On an airplane. Wireless communications can interfere with plane controls. TSA guidelines require that all electronics be turned off until the plane has reached 10,000 feet. Then, you can use a phone (or electronic) with Airplane Mode.
