It's not often that we see BlackBerry apps shown off in print advertisements, and even more rare (aka never) that said apps are still in beta. This is the case however with the latest Best Buy ad as it talks up BBM Music, although there are no real details about the app availability. Not sure who screwed up on this one, but since BBM Music is still making it's way through the BlackBerry Beta Zone, it's hard to believe that Best Buy got the go ahead from RIM to run this ad. What do you think? Drop a comment and let us know! Thanks Danny!
