The iPhone’s share of the smart phone market continues to grow, according to the latest ChangeWave survey. The survey of 3,567 consumers, which was conducted after Apple’s June 9 announcement of the iPhone 3G, showed that 11% of respondents that own a smart phone had an iPhone, up two percentage points from the previous survey, and only three points away from second-place Palm. Research In Motion’s BlackBerry continued to lead with 42% of the market. Perhaps more interesting are the responses for future purchases. Out of the respondents that plan to purchase a smart phone in the next 90 days, 56% said they were going to buy an iPhone, compared to only 29% in the previous survey (conducted in March), and far above the 23% who said they were planning to buy a BlackBerry. Finally, the iPhone also continues to lead the smart phone market in customer satisfaction, with 78% of owners reporting that they are Very Satisfied with the phone. RIM ranks second with 54% of its customers saying they’re Very Satisfied, while Palm came in last in both metrics, with results of 3% and 29%, respectively.
