Whatever happened to the actual Google Voice App for the Blackberry?
There is supposed to be a downloadable application for the Blackberry at m.google.com/voice but all I get is a "mobile" formatted version of the Google Voice website.
Make sure your browser identification is set to Internet Explorer, and then go to m.google.com/voice, and the download link should appear. When browser ID is set to BlackBerry, it takes you to the login for the mobile web version.
