According toWarren (2014): In early 2007 Steve Jobs announced the very first iPhone. Designed to “reinvent the phone,” Apple’s iPhone has revolutionized smartphones and shapes the industry into what it is today. The first iPhone mixed a capacitive 3.5-inch multi-touch display with touch-optimized software in a simple package that was unlike anything else on the market. Apple has used combinations of metal, plastic, and glass to shape and form its ideas of what a modern smartphone should look like throughout the history of the iPhone.
