IPhone

The iPhone is a line of high end smartphones, designed and marketed by Apple Inc. The first iPhone was unveiled by Steve Jobs, then CEO of Apple, on January 9, 2007, and released on June 29, 2007. The 11th generation iPhones, the iPhone 8, iPhone 8 Plus and iPhone X were announced on September 12th, 2017, and includes iOS 11, the Apple operating system for handheld devices.

An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), a camera phone, a portable media player, and an Internet client with email and web browsing capabilities, can send texts and receive visual voicemail, and has both Wi-Fi and 3G connectivity(the origuinal iPhone only supported EDGE(2G),while the iPhone 4S supports non-LTE 4G and the iPhone 5, 5C, and 5S support LTE). The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple application software is available from the App Store, which launched in mid-2008 and now has over 900,000 "apps" approved by Apple. These apps have diverse functions, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.
