Apple's iPhone and RIM's BlackBerry smartphones may be tiny players in terms of market share but they command a giant slice of mobile profits. In 2008 the two accounted for just 3 percent of all global mobile phone sales but 35 percent of operating profits, according to Deutsche Bank analyst Brian Modoff. In 2009 he estimates that the two smartphone makers will take 5 percent of the market in unit terms but 58 percent of total operating profits.
