Apple is now the single most profitable phone maker in the US, Strategy Analytics said today. Although it has just 2.5 percent share and makes just two similar iPhone models, Apple is estimated to have generated about $1.6 billion in operating profit from its cellphones in the summer where market leader Nokia said it had only generated $1.1 billion. Nokia's second-place finish comes despite it being one of the most experienced phone builders and Apple having only entered the category in 2007.
