iPhone is a line of smartphones designed and marketed by Apple Inc. They work with Apple's iOS mobile operating system. The first-generation iPhone was released on June 29, 2007, and there have been multiple iterations of new hardware with new iOS versions ever since.
The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can record video (although this was not a standard feature until iPhone 3GS), take photos, play music, send and receive e-mail, surf the web, send and receive text messages, follow GPS navigation, record notes , perform mathematical calculations, and receive visual voice mail. Other features, such as video games, reference jobs and social networks, can be enabled by downloading mobile applications. As of January 2017, the Apple App Store contained more than 2.2 million applications available for the iPhone.
Apple has released ten generations of iPhone models, each accompanied by one of the ten major versions of the iOS operating system. The original first generation iPhone was a GSM phone and established design precedents such as a button placement that has persisted throughout all versions and a maintained screen size for the following four iterations. The iPhone 3G added 3G network support and was followed by the 3GS with improved hardware, the 4 with a metal chassis, a higher screen resolution and a front camera, and the 4S with enhanced hardware and the Siri voice assistant. The iPhone 5 featured a higher 4-inch screen and the recently introduced Apple Lightning Connector. In 2013, Apple launched the 5S with improved hardware and a fingerprint reader, and the low-cost 5C, a version of the 5 with plastic colored casings instead of metal. They were followed by the larger iPhone 6, with models with screens of 4.7 and 5.5 inches. The iPhone 6S was introduced the following year, which included hardware upgrades and support for pressure sensitive touch inputs, as well as the SE, which included 6S hardware but the smallest 5S form factor. In 2016, Apple introduced the iPhone 7 and 7 Plus, adding water resistance, improved system and graphics performance, a new rear-camera configuration in the Plus model and new color options. Models.
The original iPhone was described as "revolutionary" and a "game changer" for the mobile phone industry. The latest iterations have also been praised, and the success of the iPhone has been attributed to help Apple become one of the most quoted companies in the market.
