Greg Joswiak, Apple vice president of iPod and iPhone Product Marketing, points to the fast-rising graph in cumulative iPhone sales. It was the iPhone 3G/iPod Touch v2 in June 2008 that really triggered the sales boom. As of March 2009, the iPhone and iPod Touch have sold more than 37m units.

The new iPhone 3.0 software will cost iPhone owners.. nothing. However iPod Touch owners will pay $9.95, or £5.99.

For the company that brought "cut" and "paste" to the masses in the 1980s with the Macintosh, not to having it on the iPhone was embarrassing. No longer: here's what it looks like.

An operating system is useless to developers – who write the majority of applications – without a Software Development Kit. Apple is promising more than 1,000 new APIs, the "hooks" developers can use to make their programs work better. Among the APIs unearthed in iPhone OS 3.0 is one for a magnetometer - implying that the next iPhones will have a built-in compass Photograph: Robert Galbraith/Reuters

If you've ever had a hankering to use your iPhone as a leaf trombone, help is at hand. Dr. Ge Wang of the developers Smule shows how to play music. But with the new APIs, you can have multiplayer games – or indeed music Photograph: Robert Galbraith/Reuters
