I just purchased a used HTC HD2 that has windows and android 2.2 running on it. The person I got it from didnt reset it. I have spent the last 2 hours trying to figure out how to get into android market place, but it keeps popping up for the previous person to enter their passcode. I have tried to delete it, but it will not allow me to delete. Can ANYONE help me PLEASE??? Thanks in advance!
