Okay, I cleaned this pic up a bit. If we look at the back, where the black circle is, we see that cleft clearly does NOT extend all the way to the end of the phone. Now if we look at the purple circles, these look like speaker grilles to me. The White circle, I don't know. Any ideas, folks? Almost look like softkeys or possibly branding.
If the screen moves I'd almost bet it slides in and then the part nearest those grilles goes down slightly while the part near the "rear" goes up like a pocket PC.
