Apple's iPhone is a smartphone that functions as a mobile phone, an iPod, and can run third-party apps. It runs the iOS, which is an operating system developed by Apple specifically for portable devices.

The iPhone includes a touchscreen display, which is used to control most functions of the phone. For example, you can swipe sideways on the home screen to browse through multiple screens of apps, then tap the icon of the app you want to open. Similarly, you can swipe your finger up and down in the address book to browse through your list of contacts and tap the name of the person you want to call.

While iPhone functions as both a cell phone and an iPod, its greatest potential lies in third-party apps developed for the iPhone. There are hundreds of thousands of apps available through Apple's App Store, which include productivity programs, utilities, games, and many other types of applications. These apps allow you to customize your iPhone with whatever functionality you need.
