"This is the most beautiful design you've ever seen," Jobs said as he showed off the glass-encased iPhone 4, which is apparently "24 percent thinner" than the current iPhone at just over 9mm thick.

It includes heaps of new features. One is a new five-megapixel camera. Apple promises this camera will be far better than other phone cameras at the same resolution. And in the live demo today, the cheers and applause seemed to back that up.

It'll also shoot HD video at 720p, and Apple has brought its Mac OS X editing app -- iMovie -- to the iPhone 4 for editing and sharing high-def video on the handset itself. It looks fab, though you'll have to pay for it. We expect it'll be under a fiver though.

As well, the iPhone 4's display includes a massively increased screen resolution -- 960 x 640-pixels -- with a pixel density claimed to be better than the human eye can see. That means sharper images, apps, media and text. There's also a front-facing camera for making Wi-Fi video calls to other iPhone 4 users -- not over 3G, though, sadly. This could change in the future though as mobile networks get better. It uses H.264 and Apple will make the "FaceTime" video calling app software an open standard. Theoretically, then, other phones can build in support for it for cross-platform chat.

Powering this is Apple's own A4 CPU -- the same processor found in the iPad. That, combined with a much larger internal battery, has helped Apple offer up to 300 hours of standby time, seven hours of 3G talktime, 10 hours of web browsing over Wi-Fi and 10 hours of video playback.

It runs iOS 4 -- that's right, iPhone OS 4 we've covered before, but with the "Phone" bit of the name dropped -- and includes iBooks, as featured first on the iPad, which has been updated to support Adobe PDF files natively. 

Inside is up to 32GB of flash memory, 802.11n Wi-Fi, HSDPA data connectivity, a secondary front-facing camera, GPS, accelerometer, a digital compass, and even a gyroscope for extremely precise detection of how the phone is being held and tilted.

The iPhone 4 will be launched on 24 June 2010 in the UK on O2.
