Apple iPhone Technical Specification

Whether you’re an Android user or Apple evangelist, it is difficult to deny that the immensely popular iPhone has made a mark on smartphones through its ease of use, silky-smooth web browsing, massive App Store, multi-touch screen and lack of a physical keyboard, among other reasons.

Case in point: before the first iPhone’s release, many phones sported either a sliding or clamshell design. Today, phones typically have no physical keyboard and use a multi-touch screen. The iPhone 4S may not be the first phone to use voice recognition, but its Siri app is one of the most popular, thanks to its interaction with many other iPhone applications.

From the first iPhone to the 4S, Apple has introduced innovations that have affected the way smartphones are designed. These changes may sometimes be more evolutionary than revolutionary but nonetheless, mobile phones will never be the same. See how the iPhone has changed through the years.
