The Evolution of the iPhone

We all admire the iPhones. Apple’s flagship mobile communication devices revolutionized the mobile phone industry in the late 2000s. Today, we flaunt this piece of mobile technology because of fantastic graphics, looks, and cameras. These all evolved from a modest yet revolutionary device over 14 years ago.

iPhone is by far the most sold gadget and one of the most influential too. Since Steve Jobs announcement of the iPhone on January 9, 2007, the company has sold over 1.5 billion iPhones. Since its inception, the iPhones have become pocket computers, and the world reorganized itself around smartphones.

How iPhones came into being – Project Purple

Steve Jobs essentially reimagined how people interact with their mobile devices. A touch screen device that can do multiple tasks at the effort of touch was his brainchild.

The founder of Apple Inc. requested Tony Fadell (company’s lead hardware engineer), Sir Jonathan I’ve (Design Engineer), and Scott Forstall (software engineer) to work on a top-secret project. Hence, the efforts to create an all-screen, touch-capable mobile device started in 2004 and finally materialized in 2007.
