iPhoneThe Apple device that revolutionized mobile computing and caused an explosion of smartphones worldwide. With more than a billion sold in less than a decade, the iPhone has been one of the greatest product success stories in history, catapulting Apple to the world's most valuable company. The iPhone is so popular, especially in the U.S, that it has become a substitute term for any "smartphone," whether an Apple device or not.
The latest models are the iPhone X, 8 and 8 Plus. The iPhone 7, 7 Plus, 6s, 6s Plus and SE are also available. See iPhone versions, iPhone vs. Android, iPhone X, iPhone 8 and iPhone 7.
Quite a Frenzy
No cellphone ever created so much buzz. Enthusiasts camped out overnight to be first in line when it debuted in 2007 even though it was a walled garden with little more than a dozen built-in apps and no expansion. However, in 2008, iPhone app development was opened to third parties, and the App Store took the mobile market by storm. In a few years, more than a million apps became available, and Apple pays billions of dollars in royalties to third-party developers each year. See smartphone.
Apple started the craze, and Android followed, eventually outselling iPhone around the world but not by as wide a margin in the U.S. In addition, Windows Phone and BlackBerry each added innovations to the smartphone paradigm.

Specifications and Data Service
Powered by an ARM processor, the iPhone is a GSM, CDMA or LTE cellphone that uses iOS, a custom version of the Mac OS X operating system with flash storage up to 256GB. iPhones use sealed batteries and must be sent to Apple or a third-party for replacement. Although this Apple-only feature was never popular, non-replaceable batteries have since became the norm in many Android smartphones. See iOS, ARM chips, smartphone features, carrier data plans, iPod, iPod touch, iPad, iBricking and iClone.
