The camera can also shoot 1080p video, has improved stabilisation and now supports panoramas, creating up to 28Mp images with supposedly seamless transitions.
At the front is another updated camera, which now adopts the iSight moniker. It can capture video at 720p.
Audio is improved as well. To make calls (and FaceTime) better, there are three microphones, bottom, front and back, plus a better speaker that's 20% smaller than the 4S's. There's also wideband audio support, so as long as it's supported by the network, you'll get better call quality - something the iPhone has been crying out for.
iPhone 5: Lightning dock connector
Another virtual certainty before the launch, the iPhone 5 has a new smaller dock connector, called Lightning. Wireless is now used for a lot of what a cable used to be for. It's all digital, and 80% smaller than the old 30-pin connector. Apple will offer adaptors so your old 30-pin accessories can still be used.
The headphone jack has been moved to the bottom, presumably for space reasons.
iPhone 5: pricing and availability
You can pre-order an iPhone 5 on September 14th, and it will cost the same as the iPhone 4S on contract. It will ship on September 21st.
If you don't plan to upgrade, you'll be able to get a free update to iOS 6 for most recent devices on September 19th. That includes the new iPad, iPad 2, iPhone 4 and iPhone 4S.
