A collection of concept iPhone 5 images have been uploaded by artist Antoine Bieux who has envisged the next Apple iPhone utilising Liquidmetal technology and measuring in at just 7mm thin.

The artist has also thrown in a couple of Angry Birds screens as well to help give a better idea of what games on the iPhone 5 would be like, with it's small bezal and thin form factor looking both light yet sturdy.

Of course it's just a concept, but with increasing rumours that Apple is indeed looking into Liquidmetal for the iPhone 5 it's not too far a stretch to imagine something similar to the images here.

iPhone 5: Rumours

As expected we’ve seen a strong batch of iPhone 5 rumours circulate around the web, although Apple is keeping hush about everything until the blower’s official launch date.

The next generation Apple iPhone is expected to land in late 2012, rumours suggest.

Macotakar, the Japanese Apple blog, has received word from a reliable batch of sources (or so we’re told) who claim that the Californian company will be releasing its iPhone 4S follow-up in either September or October this year.

If true, it would coincide with last year’s launch of the iPhone 4S.

Following the launch of the new iPad back in March, rumour has it the iPhone 5 could be called the ‘new iPhone’, keeping it in line with its next generation tablet.

In terms of specs, we could possibly be seeing a gorgeous 4-inch screen on the rumoured device, along with a metal back.

“The new iPhone will indeed be longer and thinner than the iPhone 4 and 4S,” iLounge editor Jeremy Horwitz said.

“Approximate measurements are 125mm by 58.5mm by 7.4mm—a 10mm jump in height, nearly 2mm reduction in thickness, and virtually identical width.” (T3)
