On Monday 07 June, as expected, Apple's CEO Steve Jobs unveiled the iPhone 4, which will be released in the US and the UK, as well as France, Germany and Japan, on 24 June.

The new phone now features a 3.5-inch Retina display that offers a resolution of 960x640 pixels - four times as many pixels as the iPhone 3GS, claims the Cupertino-based firm. "The resulting 326 pixels per inch is so dense that the human eye is unable to distinguish individual pixels when the phone is held at a normal distance, making text, images and video look sharper, smoother and more realistic than ever before on an electronic display."

The iPhone also sports a five megapixels autofocus camera, which comes with a 5x digital zoom, says Apple. The sensor is back-illuminated, and the camera is supplemented by a built-in LED flash. However, the biggest improvement over previous iPhones is the ability for users to record movies in 720p high definition 30fps mode. Apple will also release, specifically for the new iPhone, the new iMovie app, which "lets you combine movie clips, add dynamic transitions and themes and include photos and music," says Apple. The app will cost $4.99 in the US.

The iPhone 4 also offers greater battery performances, video chat capabilities, multitasking, among many other new features.

It will be available from 24 June in black or white, with retail prices starting at $199in the US. UK pricing has yet to be confirmed.
