As expected, today Apple has revealed the iPhone 5 successor dubbed the iPhone 5S. Nearly identical to the iPhone 5, Apple's iPhone 5S sports an all-aluminum chamfered-edge construction with updated hardware as well as new features. Still boasting a 4-inch Retina display, the iPhone 5S will be offered in two new flavors besides silver - gold and gray. For security, the iPhone 5S features a new highly anticipated redesigned home button made of laser-cut sapphire crystal instead of plastic which acts as a lens for the embedded Touch ID fingerprint sensor that can read your finger at any orientation.
