I live in Mexico and things don't always work that way. High end phones do seem to have a very large portion of the market, such as iPhones and flagship phones by other companies. Nevertheless low-end smartphones are also very popular. Blackberry (particularly Blackberry Curve, their cheapest model) seems to have a huge portion of the market, at least in my city (Monterrey, one of the three major cities in Mexico). Similarly, the Galaxy Ace has become extremely popular. TV is swarmed by ads of many smartphones, ranging from low-end to high-end. And even dumb-phones are still somewhat common. Our culture is obsessed with cellphones.
