Apple unveiled two new iPhones at its conference in Cupertino, Calif. Tuesday.

The first is the iPhone 5S, an updated version of the current iPhone 5. The 5S will be available in three metallic colors: gold, silver and "space gray." It was announced at the conference that the 5S would be twice as fast as its predecessor with an innovative "system-on-a-chip" embedded in the phone.

The phone also features the highly-anticipated fingerprint scanner technology. The fingerprint scanner, which is called Touch ID, replaces the passcodes and "slide to unlock" screen featured in previous models. The 5S is also the first 64-bit smartphone.

The 5S will also have more battery life than its predecessors with 10 hours of talk time, 10 hours of browsing and 250 hours in standby. The 16GB model will be selling for $199 and is available for sale on Sept. 20.

The other new phone unveiled Tuesday was the iPhone 5C. The 5C, which Apple senior vice president of worldwide marketing Phil Schiller called "unapologetically plastic" at the conference, will come in a variety of colors.

The polycarbonate phone will come in red, green, yellow, blue and white. The 5C will be selling at a minimum of $99 and pre-orders will be available on Sept. 13.

Apple also announced the release of iOS 7, the latest software update for the iPhone. The operating system features new icons and colors in addition to a new voice for Siri. The system will be available for free to iPhone users on Sept. 18.
