If you own a BlackBerry and use OverDrive, you can now download eBooks directly to your device. In addition to MP3 eAudiobooks, OverDrive's new Media Console for BlackBerry v2.1 app now supports direct downloading of EPUB eBooks. After downloading the app to your BlackBerry, use the "Get Books" feature within the app to browse and download eBooks.
In order to use this app with your BlackBerry, you must have BlackBerry OS 4.5 or newer for non-touchscreen devices or BlackBerry OS 4.7 or newer for touchscreen devices. You can download the app directly here.
