The entry-level iPhone 5 smartphone, introduced in September 2013 along with the iPhone 5S. The 5C features iOS 7, a completely redesigned OS for the first time since the iPhone's debut in 2007 (see iOS versions). Available in a pink, green, blue, white or yellow plastic case, the 5C is on par with the iPhone 5; for example, it uses the same A6 chip. The 5C includes new features such as a larger battery, improved FaceTime camera and a panorama photo mode. Offered with 16GB or 32GB storage, the 5C uses the traditional iPhone home button and not the Touch ID fingerprint reader in the 5S. It also uses a Nano SIM card, rather than the Micro SIM in previous iPhones. See iPhone 5S.
