Introduction


The iPhone 3G—3G in this case stands for third-generation mobile technology. It’s a wide-area wireless technology that allows for much faster data transmission than the EDGE network.

The iPhone 3G is more than just a fancy cell phone. Its wide range of features – from phone to web browser, from iPod to mobile game tool – the iPhone is more like a computer that fits in your pocket and your hand than any other cell phone.

The iPhone 3G is a 3.5-inch touchscreen that employs multi-touch technology. Multi-touch allows users to control items on the screen with more than one finger simultaneously (thus the name). It’s multi-touch that enables some of the iPhone’s most famous features, such as tapping the screen twice to zoom in or “pinching” and dragging your fingers to zoom out.
