Apple's newest smartphone features an updated version of its iSight camera. The revamped camera comes equipped with an 8-megapixel sensor and 3,264 x 2,448 resolution.

The iPhone 5 uses iOS 6, Apple's new operating system for mobile devices. The platform includes more than 200 new features and is also available for download for the iPhone 4 and iPhone 4S. Thanks to iOS 6, the iPhone 5 has an enhanced Siri, the phone's voice-directed interface; new mapping program; and upgraded Facebook plugin.

Although the new model is 18 percent thinner and 20 percent lighter than the iPhone 4S, the metal-backed iPhone 5 has a taller screen than its predecessor. The 4-inch "retina" display on the iPhone 5 includes 326 pixels per inch, according to CNET. With a total pixel count of 1,136x640 and an aspect ratio of 16:9, the screen provides space for a fifth row of icons.

Apple's new-gen iPhone is integrated with a number of third-party services, including applications provided by Facebook, OpenTable and Yelp. Siri, Apple's virtual assistant, allows iPhone 5 users to connect with Facebook and share information on the social network effortlessly. Apple is reportedly working with automakers to allow hands-free use of Siri.

The new iPhone 5 is displayed on Sep. 12 during a special event hosted by Apple at the Yerba Buena Center for the Arts in San Francisco.
