Both phones are equipped with front-facing cameras—1.3 megapixel on the TITAN, VGA on the Radar—confirming rumors that Windows Phone Mango would indeed support such hardware. Surprisingly, the only built-in application that can make use of the cameras is the standard camera app; it has a button for switching between the main camera and the front-facing one. Beyond that, use of the camera is up to application developers—Mango itself won't include any built-in video-calling capabilities.

The rear cameras, though they differ in resolution, both include a lens with a fast aperture of f/2.2, and the sensors are backside-illuminated, which should in principle give them better low-light performance than conventional sensors.

HTC is pre-installing some new applications, too. The phones will include an app for the HTC Watch streaming media services (already supported on Android), DLNA streaming, and Virtual 5.1 surround sound.
