"iPhone combines three products — a revolutionary mobile phone, a widescreen iPod with touch controls, and a breakthrough Internet communications device with desktop-class email, web browsing, maps, and searching — into one small and lightweight handheld device. iPhone also introduces an entirely new user interface based on a large multi-touch display and pioneering new software, letting you control everything with just your fingers. So it ushers in an era of software power and sophistication never before seen in a mobile device, completely redefining what you can do on a mobile phone. "
Multi-touch
iPhone features the most revolutionary user interface since the mouse. It’s an entirely new interface based on a large multi-touch display and innovative new software that lets you control everything using only your fingers. So you can glide through albums with Cover Flow, flip through photos and email them with a touch, or zoom in and out on a section of a web page — all by simply using iPhone’s multi-touch display.
Intelligent Keyboard
iPhone’s full QWERTY soft keyboard lets you easily send and receive SMS messages in multiple sessions. And the keyboard is predictive, so it prevents and corrects mistakes, making it easier and more efficient to use than the small plastic keyboards on many smartphones.
"Built-in Advanced Sensors
iPhone’s accelerometer detects when you rotate the device from portrait to landscape, then automatically changes the contents of the display, so you immediately see the entire width of a web page or a photo in its proper landscape aspect ratio.
The proximity sensor detects when you lift iPhone to your ear and immediately turns off the display to save power and prevent inadvertent touches until iPhone is moved away.
An ambient light sensor automatically adjusts the display’s brightness to the appropriate level for the current ambient light, thereby enhancing the user experience and saving power at the same time."
