According to Slacker, T-Mobile USA customers using BlackBerry Curve 8520 smart phones will now see an icon for the application on their phones which will trigger a download of its application. Previously, customers had to go to T-Mobile or Slacker's web site to download the application.

The firm is venture backed by Austin Ventures, Centennial Ventures, Mission Ventures, Rho Ventures, and Sevin Rosen Funds.
