The iPhone is a line of smartphones designed and marketed by Apple Inc. that use Apple's iOS mobile operating system. The first-generation iPhone was announced by then-Apple CEO Steve Jobs on January 9, 2007. Since then, Apple has annually released new iPhone models and iOS updates. As of November 1, 2018, more than 2.2 billion iPhones had been sold.
The iPhone has a user interface built around a multi-touch screen. It connects to cellular networks or Wi-Fi, and can make calls, browse the web, take pictures, play music and send and receive emails and text messages. Since the iPhone's launch further features have been added, including larger screen sizes, shooting video, waterproofing, the ability to install third-party mobile apps through an app store, and many accessibility features. Up to iPhone 8 and 8 Plus, iPhones used a layout with a single button on the front panel that returns the user to the home screen. Since iPhone X, iPhone models have switched to a nearly bezel-less front screen design with app switching activated by gesture recognition.
The iPhone is one of the two largest smartphone platforms in the world alongside Android, forming a large part of the luxury market. The iPhone has generated large profits for Apple, making it one of the world's most valuable publicly traded companies. The first-generation iPhone was described as "revolutionary" and a "game-changer" for the mobile phone industry and subsequent models have also garnered praise. The iPhone has been credited with popularizing the smartphone and slate form factor, and with creating a large market for smartphone apps, or "app economy". As of January 2017, Apple's App Store contained more than 2.2 million applications for the iPhone.
History and availability
Main article: History of the iPhone
Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1,000 employees led by hardware engineer Tony Fadell, software engineer Scott Forstall and design engineer Sir Jonathan Ive[15] to work on the highly confidential "Project Purple."[16][17]
Apple CEO Steve Jobs steered the original focus away from a tablet (which Apple eventually revisited in the form of the iPad) towards a phone.[18] Apple created the device during a secretive collaboration with Cingular Wireless (which became AT&T Mobility) at the time—at an estimated development cost of US$150 million over thirty months.[19]
According to Steve Jobs, the "i" word in "iMac" (and therefore "iPod", "iPhone" and "iPad") stands for internet, individual, instruct, inform, and inspire.[20][21]
Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Among other deficiencies, the ROKR E1's firmware limited storage to only 100 iTunes songs to avoid competing with Apple's iPod nano.[22][23]
Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six.[32] Apple released the iPhone 3G in upwards of eighty countries and territories.[33] Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the US, Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost,[34] and 40% of users had household incomes over US$100,000.[35]

The back of the original first-generation iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal.[36] The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. The iPhone 3GS was available in both colors, regardless of storage capacity.
