Nokia's share of the market for smartphones -- handsets with computer-like features like e-mail -- fell to 38.9 percent in the quarter from 51.4 percent a year before, Canalys said.
However, Apple's market share jumped to 17.3 percent and RIM's to 15.2 percent in the quarter.
"The introduction of the iPhone 3G in July and Apple's expansion into many more countries helped propel the vendor to second place globally," Canalys said in a statement."
