I digress slightly, but what would really be cool, is if there was an app that replicated the functionality on the Touch Pro 2. When you turn the Touch Pro 2 on it's face, the speakerphone automatically turns on, and when you turn it back over, it disengages. You can then see the phone screen and interact with it however you wish (hang up call, dial digits, etc). I believe they use the light sensor to detect this. There's also a mute button on the back of the phone if you want to mute the call without flipping the phone over.
