The most interesting point in the article to me:

"AT&T’s wireless unit, Verizon, T-Mobile USA and Sprint Nextel [t]ogether ... control 96 percent of United States sales of mobile devices ... "

"In Europe, a competitive marketplace with more than 230 operators, Nokia could always find one or more operators in every domestic market willing to sell its portfolio of phones.

"But in the United States, where a small number of operators rule most of the market, the network companies can command design changes to promote and sell their own wireless services. They place their own brand names on every model they sell and make sure their revenue-raising wireless services are prominently displayed and easy to use."

In other words, Nokia is used to playing in a competitive marketplace, not in the oligopoly of the supposed Land of Free Market Competition.
