Nokia Windows Phone 8 prototype device leaked

Here we are with another new leak – this time it is Nokia’s unnamed Windows Phone 8 device, a yellow coloured unibody protoyype smartphone as reported by sources.
Chinese website WPDang has released pictures of the mystery device that looks like the current Nokia Lumia phones. As per the leaked pictures and information, the device features a unibody polycarbonate design with a fine yellow-border finish, not seen on the current Lumia series smartphones.
Here’s the picture released by WPDang:

The new device, although still a prototype, could be the extension of Nokia Lumia 800, as it shows remarkable similarity with the popular curved-screen phone.
As far as the operating system and user interface of the new prototype is concerned, SlashGear offers the following interpretation of the information released on the Chinese website:

The UI also marks the unnamed phone out as potentially something special. The smaller iconography – which now fits up to four Live Tiles to each line – is a feature of Windows Phone 7.8 and Windows Phone 8; it’s unclear which version of the platform this device is running or, indeed, if it’s merely showing a screenshot of the updated interface.

There is no confirmation as yet about whether or when this Nokia device will be made available. However, Nokia is expected to release first two Windows Phone 8 handsets early next month.
