Potencial way to market BB products!
I came across this video on youtube, it's by Indian Punjabi hip-hop artist's and was released before BB10 launch.

The point I am trying to make here, Blackberry can use these kind of mediums to promote their products, tie up with known 'Artists' according to the regions and there you go. It seems to be an attractive way to promote their products and also a creative way, or maybe they need some other way, along with adverts which are informative. Blackberry's current marketing is not very convincing.
Perhaps stepping out of their comfort zone and trying something new.
