Steve Jobs
Apple began work on the first iPhone in 2005 and the first iPhone was released on June 29, 2007. The iPhone created such a sensation that a survey indicated six out of ten Americans were aware of its release. "Time" declared it "Invention of the Year" for 2007. The completed iPhone had multimedia capabilities and functioned as a quad-band touch screen smartphone. A year later, the iPhone 3G was released in July 2008 with three key features: support for GPS, 3G data and tri-band UMTS/HSDPA. In June 2009, the iPhone 3GS, whose improvements included voice control, a better camera, and a faster processor, was introduced by Phil Schiller. The iPhone 4 is thinner than previous models, has a five megapixel camera capable of recording video in 720p HD, and adds a secondary front-facing camera for video calls. A major feature of the iPhone 4S, introduced in October 2011, was Siri, a virtual assistant capable of voice recognition.
Face ID
Apple announced Face ID during the unveiling of the iPhone X on September 12, 2017. The system was presented as the successor to Touch ID, Apple's previous fingerprint-based authentication technology embedded in the home button of the iPhone 8 and earlier devices. On September 12, 2018, Apple introduced the iPhone XS and XR with faster neural network processing speeds, providing a significant speed increase to Face ID. On October 30, 2018, Apple introduced the third generation iPad Pro, which brings Face ID to the iPad and allows face recognition in any orientation.
