According to NPD, an aggressive "buy-one-get-one" promotion by Verizon Wireless helped RIM's BlackBerry Curve move past Apple's iPhone to become the best-selling consumer smartphone in the U.S. The firm said RIM's consumer smartphone market share increased 15 percent to nearly 50 percent of the smartphone market in the first quarter of this year compared with the previous quarter.

NPD Group said it arrived at its numbers by collecting more than 150,000 completed online consumer research surveys each month. "Surveys are based on a nationally balanced and demographically representative sample, and results are projected to represent the entire population of U.S. consumers," the firm said. The figures do not include "corporate/enterprise mobile phone sales."
