Strategy Analytics believes Apple to have became the world’s most profitable handset vendor in Q3 2009. Nokia slipped into second position, with its profit margins hurt by the economic downturn and sales stagnation in the US.Alex Spektor, Analyst at Strategy Analytics, said, “We estimate Apple’s operating profit for its iPhone handset division stood at $1.6 billion in the third quarter of 2009. Apple overtook Nokia for the first time, which recorded a lower $1.1 billion of operating profit.
