New images of a potential iPhone 6 design have been created based on an alleged test prototype, sporting a similar shape to the latest iPod nano.

A designer at CiccareseDesign created the 3D mockup to show what he thinks the iPhone 6 could look like, and has published a gallery of images showing various angles and colours of the device. "It's a possible iPhone 6 version, it is a remake from a test prototype description," the designer explained.

The designer, who has published concept designs for various Apple products in the past including an Apple 'iScreen' and even a little device called an 'iSiri' that would allow users to control iOS devices via Siri without removing them from bags or pockets, notes that the next iPhone could run what he calls 'iOSX', an operating system that he thinks could fuse iOS and OS X together. 

Apple has been closing the gap between iOS and OS X with its latest versions, adding iOS features like Notifications and Game Centre to OS X 10.8 Mountain Lion, and adding new functionality to iCloud.

CiccareseDesign's concept also shows a landscape Home screen on the iPhone, a feature that has so far been portrait only. The landscape Home screen has an extended dock with six icons.

The latest speculation from around the web suggests that Apple will launch its iPhone 6 (or iPhone 5S) in May, with eight colour options and three different screen sizes.
