I guess this constitutes news (and I apologize if it's already posted):
From the OverDrive blog:
OverDrive’s BlackBerry app now supports EPUB eBooks
"Today we released OverDrive Media Console for BlackBerry v2.1, which adds support for direct EPUB eBook downloads from your library. Like OverDrive’s apps for Android, iPhone, and iPad, this app includes a “Get Books” feature so that users can easily find your library. From there, users will be able to browse the mobile version of your Virtual Branch website, check out an EPUB eBook or MP3 audiobook with a library card, and download the title directly to their BlackBerry device.
The free app is available on OverDrive’s software page and in the MobiHand Superstore, and can be installed on BlackBerry touch-screen devices running BlackBerry OS v4.7 or newer and non-touch-screen devices running BlackBerry OS v4.5 or newer. (That covers about 96 percent of all active BlackBerry users.) We also expect the app to appear in BlackBerry App World in the coming weeks."
