Sales of Chinese iPhones have been "somewhat disappointing," says Morgan Keegan's Travis McCourt. The analyst claims that while the smartphone market has "exploded" in China during 2010, growing 200 percent year-over-year, Apple and BlackBerry maker RIM sold less than 500,000 phones last quarter. BlackBerries, in fact, are still only being sold to government and businesses in the country, according to McCourt. Apple and China Unicom have not officially announced recent iPhone numbers.
