A new report released on Monday by Strategy Analytics shows that Apple’s U.S. smartphone market share is on the rise, while Android declined in the second quarter of 2012.

Apple’s market share rose significantly, rising 10 percentage points from 23 percent to 33 percent, when compared to the second quarter of 2011. Android’s share fell 4 points to 56 percent. Of course, it’s important to note that hundreds of devices use Android, while Apple only has a couple of iPhone devices on the market.

BlackBerry fell 4 points, coming in with 7 percent of the market, the lowest in recent years for the company.

Overall smartphone shipments fell 5 percent, which Strategy Analytics blamed on a “volatile economy, maturing penetration of smartphones among contract mobile subscribers, and major operators tightening their upgrade policies to enhance profits were among the main causes of the slowdown.”

Update: Changed Apple’s 10 percent rise to 10 percentage point rise.
