The iPhone is a smart phone created by Apple that combines a mobile phone with an iPod. With an iPhone you can also browse the Internet, manage your email, manage your daily appointments, check stock prices, check the weather, watch YouTube videos and more. The iPhone looks different than a traditional mobile phone due to the fact that it relies on a touch-screen interface rather than traditional buttons.
