I'm currently on 2.1 (telus rom) and I would like to update to 2.2 using the OTA stock HTC rom included in the message board however I want to ensure check to see if the Desire HD 2.2 is the same as Desire 2.2 and there are any differenced then what are they? I saw some cool features on the Desire HD video, like the save maps offline, is that available on the Desire 2.2 update?
