I see that there is a HDMI port on this phone with connectivity supported. I also read that there is a multi feature home "dock" available and one of it's features is managing the HDMI function. Am I understanding this correctly when interpreting that the dock is a needed go-between for the HDMI to work, or can I just just plug the phone directly into the TV/Projector/etc. with a cable? Perhaps the dock adds features?
