HTC HD2 doesn't qualify for a Windows Phone 7 upgrade
Bad news for the HTC HD2 owners: your beloved WinMo smartphones does not qualify for a Windows Phone 7 upgrade. The reason is more than ridiculous but you can't do anything to change the situation: the HD2 packs five hardware buttons instead of only 3.
Yeap, the HTC HD2 has a zippy 1GHz Snapdragon processor, a huge capacitive touchscreen display of high resolution and lots of other goodies but according to a Microsoft representative the HD2 "doesn't qualify because it doesn't have the three buttons [layout]".
According to another MS spokesman, the reason for HD2 to skip the upgrade to Microsoft's latest OS for mobile devices is actually the lack of some hardware components.
