The HTC HD2 is famous for running every OS ever written, and now the latest to add to that is full Windows RT.
Out-of-the-box thinking from a guy @Cotulla
is the reason why HTC HD2 runs on Windows RT. Cotulla and the guys out in the company have a long track-record of doing extra-ordinary things and HD2 is certainly no exception. It has happened now and the company deserves a round of applause for its attempt.
This innovation has left HD2 as the most hacked mobile devices at the moment. HTC has also contributed in opening the kernel and boot loader and has made the field open for the hackers to play. HD2 lived beyond the repeated porting from one OS to the other.
