The Incredible specific windshield mount is available from Verizon, even though it doesn't show up on their website. Just call in and ask for it, and the rep can look it up and order it for you. I have mine on the way, and it should be here Monday. They are also showing the desktop charging cradle, in the system, but not in stock, yet.
@Spotmark - Did you get this yet? How is it? I would really like to get a car/windshield mount that is specific to the D-inc. so that it doesn't cover any ports or push buttons (like the universal mounts). However, I'm hesitant to order one sight-unseen from Verizion. I don't see why they just can't put the darn thing on their website!
Edit: I see you posted this in May, but as of today (July 8th) they still don't show it on the website.
