Acer has unveiled it's W4 handset which is the first handset as yet to have Microsoft's Windows Phone 7 Mango update out of the box.
The W4 is not a phone designed to break records however, boasting just a 1GHz Qualcomm processor, 8GB storage and a 5MP snapper.
Of course what the main attraction will be is the inclusion of Windows Phone 7 Mango out of the box, the OS update which contains hundreds of minor and major tweaks to Microsoft's mobile operating system.
