The iPhone, the biggest open secret in the world apart from Britney Spears' private parts, was officially unveiled in January 2007. Apple CEO Steve Jobs claimed it will 'revolutionise' the phone.

The handset combines the functions of a phone with that of the phenomenally successful iPod. It is also a handheld computer with Wi-Fi compatibility and comes with Apple's OS X operating system and Safari web browser. A 2-megapixel camera is inbuilt and it features a wide 3.5-inch (9cm) touch screen.

It will be available in two sizes, 4GB or 8GB of memory for videos and songs. The phone is less then one centimetre thick and comes in the standard iPod chrome casing with a black facia. It will also be completely touch screen and you can browse through your music by album artwork.
