While the official reply from Microsoft seems to be fixed that HTC HD2 will NOT get Windows Phone 7 OS as it does not match the basic requirement for the new OS. Nevertheless, fans of HTC HD2 did not stop on it and finally, developers from Russia were able to port the new Windows Phone 7 OS into HD2.
According to the report, all the functions of the Windows Phone 7 seems to be working fine on HTC HD2 except the graphics driver. There is also a noticeable device lag after installing the Windows Phone 7 Series OS.
This is a much needed good news for HTC HD2 owner. Although I seriously doubt that the performance will get any better with the current hardware.
