The Apple iPhone 5 looks a lot like the iPhone 4S but it's thinner, by 18 per cent, and lighter, by 20 per cent. The screen is taller too, at 4-inches corner to corner, but the phone, held in portrait mode, is the same width. Instead of a glass back, the iPhone 5 back and sides are made from a single piece of aluminium.
The handset is powered by an A6 processor, an upgrade from the A5 chip in the iPhone 4S and the A5X in the latest iPad. Apple says the A6 delivers CPU and graphics performance that is twice as fast as the iPhone 4S.
Though the camera is still 8-megapixels, Apple says that performance will be improved by the new A6 processor. The iPhone 5 also has better low-light performance and a new panorama mode.
The iPhone 5 will work on EE, the new 4G network from the company formerly known as Everything Everywhere. That network will launch within the next few weeks but prices and speeds are yet to be confirmed. If you are on another network then you're out of luck: those networks have to wait for the spectrum auction before they can start their 4G services and they are unlikely to arrive before next summer.
