NewPCGadgets has something with the MobileRiser but the Mobile Visor is just a bit much. (though still not close to the Crocs O-Dial) It is essentially a hood for your BlackBerry to block out the sun and nosy people trying to catch a look of your screen. For $8.95 it attaches to your BlackBerry with a rubber band and has a little folding canopy that sits above your screen.
I just can’t imagine using it myself but I am curious to see if anybody has a use for such a thing. You can easily take it off and it folds flat to the size of a credit card. Check it out at this link.
