Anecdotally, RIM has been making significant inroads amongst the smartphone-buying youth in South Africa by heavily advertising BBN and offering discounted models. Whether this will prove sticky enough in the end and whether it's applicable elsewhere are open questions, but every single one of the sub-25 year olds I know who had the choice of getting a premium phone opted for a Blackberry instead of an iPhone or Android device, and they did it purely because of BBN.
