The Ruby can be seen reflected into the Flyer's display. In fact, there are two Rubys that appear in the images. Unfortunately, only the back of the handset is unveiled. We can see a camera (apparently with dual LED flash), and a 3.5mm headset jack, and… that's about it.
What we certainly can not say is what OS the HTC Ruby is running. It could be Android, Windows Phone, or even Brew (HTC has some Brew phones, too). In any case, the handset surely is interesting, and we'll try to find out more about it as soon as possible.
