Although there has been no official release date for the Windows Phone 7, apart from Microsoft saying it will be ‘holiday 2010′, it would seem that we might be able to get more specific than that.

Australian carrier Telstra have leaked a snippet from what seems to be an authentic Telstra roadmap which shows the Windows Phone 7 based HTC Mozart to be launched sometime in October.

Ubergizmo have revealed that although the picture is a Photoshopped version of the HTC Desire, the HTC Mozart is an actual device which is due to be released in October. It has also been suggested by Engadget that the device is heading to T-Mobile in the US.
