You should read the whole article again. The author didn't just present the data; she suggested that mobile phones are linked to socio-economic status. For example: "Among other things, cell phone brands say something about socio-economics – it takes a lot of money to buy a new iPhone 5 (and even more money to keep up with the latest models that come out faster than plan upgrades do)." While it's true that iPhones cost more, they do not necessarily say something about socioeconomic status. Wealthy consumers may be frugal and purchase less expensive phones; less wealthy consumers stretch their budgets to buy iPhones.
