GoPro ProTune firmware went "live" today but unfortunately only an option for HD2. Also the iPhone App is available as well.
Update your HD2 camera firmware via Cineform Studio to get ProTune and if required, Download the App from iTunes thru your iPhone for remote control and preview functionality via the wiFi bacpac.
Enable ProTune under settings/ more menu.
