Several websites have published this video of a mystery BlackBerry. The video on YouTube is titled, "BlackBerry Bold 9980 (R47) Hands-on Walk-through," suggesting it's a prototype for a 9900 series BB. Frankly, it looks like a very old prototype with its squairsh looks and silver frame, but it's interesting none the less.

Some rumors have suggested this device was designed by Porsche, but I find that very hard to believe. It looks more like it was designed by Sony to me.

You'll notice this BlackBerry does have a touchscreen so perhaps it is a 9900 series prototype.
