iPhone combines three amazing 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.

Widescreen iPod

iPhone is a widescreen iPod with touch controls that lets you enjoy all your content - including music, audiobooks, videos, TV shows, and movies - on a beautiful 3.5-inch widescreen display. It also lets you sync your content from the iTunes library on your PC or Mac. And then you can access it all with just the touch of a finger

Revolutionary Phone

iPhone is a revolutionary new mobile phone that allows you to make a call by simply pointing your finger at a name or number in your address book, a favorites list, or a call log. It also automatically syncs all your contacts from a PC, Mac, or Internet service. And it lets you and listen to voicemail messages in whatever order you want - just like email.

Breakthrough Internet Device

iPhone features a rich HTML email client and Safari - the most advanced web browser ever on a portable device - which automatically syncs bookmarks from your PC or Mac. Safari also includes built-in Google and Yahoo! search. iPhone is fully multi-tasking, so you can read a web page while downloading your email in the background over Wi-Fi or EDGE.

High Technology

Multi-touch - a human-computer interaction technique and the hardware devices that implement it, which allow users to compute without conventional input devices (e.g., mouse, keyboard). Multi-touch consists of a touch screen (screen, table, wall, etc.) or touchpad, as well as software that recognizes multiple simultaneous touch points, as opposed to the standard touchscreen (i.e. computer touchpad, ATM), which recognizes only one touch point. This effect is achieved through a variety of means, including but not limited to: heat, finger pressure, high capture rate cameras, infrared light, optic capture, tuned electromagnetic induction and shadow capture.
A myriad of different applications for multi-touch interfaces both exist and are being proposed. Some uses are individualistic (e.g., iPhone, iPod touch, MacBook Pro, MacBook Air). However, multi-touch technology is mainly used to incorporate collaboration into the computing experience.
