Apple has finally announced its iPhone 5 smartphone after months of rumour and speculation.
As expected, the firm has shown off its next-generation iPhone and, unlike last year's disappointment when Apple announced the iPhone 4S, this time it really is the widely expected iPhone 5.
The design of the iPhone 5 is larger than previous iterations, as indicated by the first case which was announced by Sculpteo before the launch event.
iPhone 5: screen
The main reason for this is the larger 4in screen which has a 1136 x 640 resolution (that's 326ppi - the same as the iPhone 4S with its 3.5in 960x640 resolution). It's the first time Apple has used a screen size other than 3.5in for the iPhone, and also the first with a 16:9 aspect ratio.
This means there's room for a fifth row of icons on the Home Screen, and allows more information to be shown in apps such as Mail and Calendar. All of Apple's apps are being updated to make better use of the screen real estate including iMove, GarageBand, iPhoto, Keynote, Pages and Numbers.
Some apps will remain unchanged, such as the App Store. This will be shown centred with black borders above and below. Of course, videos also appear larger because of both the bigger diagonal, and the wider aspect ratio which minimises the black bars.
The screen has 44% more colour saturation, and has the touch-sensitive layer integrated into the display itself, removing a layer and making it sharper.
iPhone 5: wireless
One detail which was almost a certainty before the launch event is support for 4G in the UK, so you'll get up to 5 times the download speeds of a 3G iPhone 4S. The iPhone 5 will work on EE's 1800MHz 4G mobile network when it becomes available to the public in a few weeks' time. See also: EE 4G in the UK: what you need to know.
Plus, it has new dual-band Wi-Fi, operating on both 2.4GHz and 5GHz. This means you could get a stronger signal from hotspots or home routers which also have dual-band capabilities.
iPhone 5: performance and design
The main chip has also been updated, as expected, to the Apple A6 processor. Apple claims it's twice as fast as the A5 (including graphics performance), yet is 22% smaller.
Despite the bigger screen, the new iPhone 5 is 20% lighter than the iPhone 4S at 112g. It measures just 7.6mm thick, and is constructed entirely of aluminium and glass. That's not great news for anyone hoping the iPhone 5 would be more durable.
iPhone 5: cameras and audio
The camera has been improved with an 8Mp back-illuminated sensor. To counteract the impact of a thinner lens, there's more precise lens alignment and sapphire crystal glass. The faster processor also means faster photo capture, and better processing for better low-light performance.
