Somebody please give me hope and tell me that I will be able to get rid of Windows and change the OS to android!!! I'm am so upset. I had the Tmobile G1 and loved it but I went into the Tmobile store last Saturday to upgrade a different line and I saw the HTC HD2 and had to have it. Unfortunately I didn't pay attention to the OS because I didn't even know that there were different kinds. I just figured that all Tmobile phones used android. I hate the OS on this phone and am thinking about switching back to my G1 for the meantime. Can the android OS be put on this phone?
