In January 2007, Steve Jobs and Apple Inc. introduced their first iPhone in his speech at the Macworld conference and exhibition. At the time, in Jobs' hands, it looked like a sleek black rectangle. Then Jobs touched the object on the screen. Suddenly, the object transforms into an interactive surface. Jobs placed a function with his fingertips in the form of arrows on the screen and swiped from left to right. When his finger moved, the arrow moved. For some people, the interaction between a human finger and an image on the screen is more amazing than all the other features combined. Apple Inc. shocked the world on June 29, 2007 by deciding to openly compete in the mobile phone industry. Apple exclusively chooses AT&T Wireless as its partner to market the iPhone 2G. During initial development, Apple wanted to create an iPhone mobile device that combined the entertainment features of the iPod with cell phone communication. Additionally, the iPhone 2G comes with a 2-megapixel camera for documentation purposes. In some ways, the iPhone is more like a handheld computer than a mobile phone. Like most smartphones, you can use it to make and receive calls, listen to music, watch movies, browse the web, or send and receive emails and text messages. You can also take photos and videos (using iPhone 3GS or other models) with the built-in camera, import photos from your computer and manage them using the iPhone app. iPhone Product DevelopmentiPhone iPhone is a product created by Apple Inc. which very appalled the world when it first appeared in 2007.
