The SIRIUS/XM app for BlackBerry has been available in the US since early February, 2010. The app is an extension of the premium paid service, and gives you 120 channels, just like on the iPhone app. We’ve learned that the app is now available in Canada, so feel free to check it out and download for your device.
Update: This software can utilize both the BlackBerry Bluetooth Stereo Gateway and the BlackBerry Visor Mount. If you’ve already paired the device, it’ll work without the need for further configuration.
