AatmaStudio has released a cool concept video for the iPhone 5. It looks awesome, but how likely is it that the iPhone 5 could actually have the features shown in the video? Ultra thin design, for example, might be possible. Smartphones are getting thinner and thinner, with the title of the world’s slimmest smartphone currently held by the Medias N-04C from Japanese company NEC Casio Mobile. At 7.7mm, the Android handset beats both the Galaxy S II and iPhone 4 when it comes to slimness.
