MapBox has posted an interactive Twitter visualization that shows a heatmap of smartphone Tweets by region, broken down by smartphone brand. It shows the iPhone (red) dominating in affluent areas and Android (green) in poor regions. Blackberry (purple) use is predominantly outside of major cities and in Africa, Central America, Southeast Asia and the Middle East. Pictured above is a map of Washington, Philadelphia and New York showing a heavy bias toward Tweets from iPhones.
Mobile Devices is a map that reveals the information about phone brands that is stored when people use an official Twitter App and is hidden in the metadata attached to each tweet. Each brand of phone is a different color and can be independently toggled. The patterns of usage in each city often reflect economic stratification. For example iPhones, in red, are predominantly in wealthy sections of the city while Android phones, in green, have more coverage in poorer sections. On a global level, national trends reveal a complicated set of cultural preferences. (Tweets from web browsers and from other Twitter clients don’t appear on this map)
