Three years ago Apple announced their first “iPhone” which completely change cellular industry and once again initiated a tough and never ending competition from other players like Nokia, HTC, BlackBerry, Sony Ericsson, Samsung & LG. The iPhone not only set the precedent for others but also with its revolutionary operating system changed the whole world and started an era of Google’s Android platform and Palm’s webOS.

Tomorrow on June 7th 2010 WWDC (Apple Worldwide Developers Conference) will be held at Moscone Center West in San Francisco. Steve Jobs will present iPhone 4G officially. But before that lets us quickly glance at past and see what iPhone was all about.
