High Technology
iPhone redefines what a mobile phone can do. That’s because it integrates pioneering hardware technology with the world’s most advanced mobile operating system.
Multi-Touch
With its large Multi-Touch display and innovative software, iPhone lets you control everything using only your fingers. How does it work? A panel underneath the display’s glass cover senses your touch using electrical fields. It then transmits that information to an LCD screen below it. The display also features an oil-resistant coating that keeps the iPhone screen clean.
Accelerometer
iPhone responds to motion using a built-in accelerometer. When you rotate iPhone from portrait to landscape, the accelerometer detects the movement and changes the display accordingly. The accelerometer also gives you amazing game control.
3G
3G technology gives iPhone fast access to the Internet and email over cellular networks around the world. With support for 7.2Mbps HSDPA, iPhone 3GS also makes it possible to do more in more places: Surf the web, download email, get directions, and watch video — even while you’re on a call. Since iPhone seamlessly switches between EDGE, faster 3G, and even faster Wi-Fi, you always get the fastest connection available. You can even share your Internet connection with your laptop via Internet tethering.1
Sensors
When you lift iPhone to your ear, the proximity sensor immediately turns off the display to save power and prevent accidental dialing. The ambient light sensor in iPhone automatically brightens the display when you’re in sunlight or a bright room and dims it in darker places.
