Do you mean word-of-mouth advertising? You DO understand that it CAN work--but only when you have a compelling device that people can convince others with. Nokia hasn't done ANYTHING right with regard to that--they pretty much communicate terribly, offer the worst warranties and customer support that local laws will allow, and do nothing as far as I can tell to provide something better than their competition--in fact providing far worse experiences than competing devices on the market. The only thing they seem to have going is that they sell far more cheaper devices around the world. Well, at least they do SOMETHING right. Certainly nothing worthy word-of-mouth advertising, if that's what you meant.
