Happy 5th birthday to iPhone and what an amazing 5 years it has been. The late Steve Jobs launched the first to great fan fair on 9 January, 2007 in the US. The original iPhone introduced the concept of a smartphone - a mobile phone that could browse the full internet, not just WAP pages, which had more in common with a computer than a phone. Here is Steve in his trademark black roll neck talking about the first iphone.

And here is Steve one year on where Apple announced the next iPhone - named 3GS - at its Worldwide Developer Conference in June, 2009.

Selling 1.7 million units in its first three days, the iPhone 4 quickly become Apple's most successful product launch in history.

Following the death of Steve Jobs in 2011 here is Apple Senior VP Worldwide Product Marketing Phil Schiller launching the iPhone 4S at the company's "Let's talk iPhone" event at Apple headquarters on October 4, 2011.

The iPhone is the iconic device of the 21st century. Revolutionising how we communicate. And the final word from the late head of Apple, Steve Jobs, just about sums it up, as he said 'people often don't know what they want, until you show it to them. And it seems that now we've been shown, we know just what we want.
