According to August data from The Nielsen Co., Android is now the most popular operating system among people who bought a smartphone in the past six months, while BlackBerry and Apple iOS are in a statistical dead heat for second place among recent acquirers.
Nielsen says the data covers a period that includes a full month of iPhone 4 availability, which launched at the end of June.
Of just over 1,744 consumers who bought smartphones in August, 34 percent bought Android devices, while 25 percent bought iPhones and 26 percent bought BlackBerry devices.
Among all smartphone owners, BlackBerry still holds the dominant share in the United States, with 31 percent of the market, though its lead over Apple is declining.
Twenty-eight percent of smartphone owners have Apple iPhones, compared with 19 percent who have Android devices.
