There isn't one. As of right now, this is not for our devices. I went to the Sprint mobile site and the Vision site on my Mogul and there are no links or even a Windows Live Search bar as stated on the article.
However, from reading comments on the Engadget article, users with other phones (Samsung A900) that are not PDAs get a message that there's an upgrade happening on the Vision site.
This leads me to believe that only phones like the RAZR, A900, etc. will be able to use this application. Something tells me this will be rolled out as J2ME first and then maybe we'll get a WM version.
Keep in mind we already have a Live Search WM app on our devices, and even though it cannot triangulate our position with the nearby cell towers, they may not see WM users as a priority.
I hope I'm wrong... but this is usually how it happens
