Smartphone volumes during the quarter rose due to record sales of Apple iPhones. As a result, Apple became the third-largest mobile phone vendor in the world; overtaking LG. Apple also became the world's top smartphone vendor, with a market share of 23.8 percent in the fourth quarter of 2011, and the top smartphone vendor for 2011 as a whole, with a 19 percent market share.
Roberta Cozza, Principal Research Analyst, Gartner said, "Western Europe and North America led most of the smartphone growth for Apple during the fourth quarter of 2011. In Western Europe the spike in iPhone sales in the fourth quarter saved the overall smartphone market after two consecutive quarters of slow sales."
