In January 2007, Steve Jobs introduced the Apple iPhone during his keynote address at the Macworld Conference and Expo. In its first appearance on screen and in Jobs 's hand, the phone looked like a sleek but inanimate black rectangle.
Then, Jobs touched the screen. Suddenly, the featureless rectangle became an interactive surface. Jobs placed a fingertip on an on-screen arrow and slid it from left to right. When his finger moved, the arrow moved with it, unlocking the phone. To some people, this interaction between a human finger and an on-screen image was more amazing than all of its other features combined.
WHAT CAN WE DO WITH IPHONE?
In some ways, the iPhone is more like a palmtop computer than a cellular phone. As with many smartphones, you can use it to make and receive calls, watch movies, listen to music, browse the Web, and send and receive e-mail and text messages. You can also take pictures and video (using an iPhone 3GS or later model) with a built-in camera, import photos from your computer and organize them all using the iPhone 's software.
IPHONE
The basic idea is pretty simple -- when you place your finger or a stylus on the screen, it changes the state that the device is monitoring.
STRUCTURE OF THE IPHONE
The iPhone is a flat, rectangular phone with a touch screen and a camera lens. The narrow outer edges have several controls and plug receptacles. The off and on button is located on the right side, with the receptacle for the earphone to its left. The receptacle for the recharger is on the opposite end of the phone. On the left side are the sound controls. The long button controls the volume, and the smaller button above it, is the mute control. When it displays a red dot, the phone 's ringer is muted. It is fairly easily to accidentally mute the ringer, and users often overlook this control and wonder why their phone is not ringing.
Four icons are located at the bottom of the screen: phone, mail, safari
