Slacker and Research In Motion announced plans for Slacker to provide a free Slacker Personal Radio application, exclusively for BlackBerry smartphones, that will enable listeners to hear their favorite Slacker radio stations wherever they go–even when not connected to a wireless network.

The Slacker application will provide BlackBerry smartphone users in the U.S. with a robust, high-fidelity personalized music discovery and listening experience pulling from over 100 expertly programmed Slacker stations, over 10,000 artist stations or their own custom-created stations.
