On January 9, 2007, at Macworld, Steve Jobs pulled a tiny device out of his pocket, introducing the world to the phenomenon called the iPhone. The iPhone first went on sale on June 29 that year, and it has been an eventful journey since then. A look:
The device introduced the icon grid layout, a single home button and a multi-touch display. While it wasn’t targeted specifically at enterprises, it did drop the physical keyboard and stylus, either or both of which were present on most mobile devices for that segment then. And it offered “pinch-to-zoom”, a feature we take for granted these days.

This device introduced the App Store, giving third-party developers a chance to build applications for Apple’s phone. This ultimately led to the popularity of the app-based ecosystem, apps for enterprises also started appearing soon. This phone also supported faster 3G data speeds, push email and GPS navigation, which is a given on any smartphone today.
