Apple Unveils iPhone 5

Upgrade is larger, lighter, and faster

Apple has unveiled a taller, 4G-enabled iPhone at an event in San Francisco.

The device's new size allows it to display an extra row of app icons on its home screen.

The firm said it was 18% thinner and 20% lighter than the iPhone 4S. The screen measures 4in (10.2cm) which is still smaller than rival devices from Samsung, Nokia, Motorola and HTC.

It said it would be available on 4G via Everything Everywhere (EE) in the UK.
