Kobo unveiled a new social e-reading app for BlackBerry smartphones at the BlackBerry World conference currently being held in Orlando, Florida. The app ties into BlackBerry's BlackBerry Messenger (BBM) platform, which lets developers build social networking apps for BlackBerry (the platform is still in beta).

The Kobo eReading App for BlackBerry smartphones lets readers hook into various social networking functions while reading and buying e-books. The app's functions include the ability to see whether BBM friends own e-books the are shopping for, chat with friends and browse friends' Kobo libraries.

The app is not currently available in wide release, but attendees at the conference had opportunities to see it demonstrated and try at the Kobo booth.
