Motorola (MOT) kept its lead in US market share by holding 25.8% of the country’s cellular phone business. That was hardly the big story.

Research-In-Motion (RIMM), maker of the Blackberry, was the significant winner in the second quarter. According to Reuters, "BlackBerry cornered 10 percent of U.S. cell phone sales in the second quarter in a market that grew more than 5 percent despite economic concerns, Strategy Analytics said on Monday."

The figures leaves open the question of where Apple (AAPL) will pick up market share for its iPhone, which seems to be selling well in a industry which is only expanding at a crawl. It certainly makes it likely that Nokia (NOK), LG, and Motorola are likely to lose part of their smart-phone business down the road.
