The HTC HD2 has been caught running on both Windows Phone 7 and Android in the past, although having both running simultaneously has never been achieved – not until now. Of course, we don’t mean that the two mobile operating systems run at the same time literally, but folks over at xda-developers managed to find out a way to install both Windows Phone 7 and Android on the HD2, running off a similar SD memory card. Of course, the method isn’t easy at all, but then again what is life if there is no challenge at all? You can always check out the methods at your own risk, and if you have the programming nous and intestinal fortitude, go ahead. Do leave us a comment on your experience.
