Consumers and business users alike prefer it over the BlackBerry

Here's a bullet point you can expect to see at Steve Jobs' next keynote.

Apple's (aapl)  iPhone has once again come in first in J.D. Power's semi-annual customer satisfaction study, despite a battery that continues to disappoint.

Apple increased its score in both the consumer and business user portions of the survey.

Research in Motion's (rimm) BlackBerry was No. 2 among business users and No. 3, after Apple and LG, among consumers.

More broadly, the survey found:

  • Smartphone owners are happier: Consumer satisf action is up 14 index points (on a scale of 1,000) from six months ago; business owners are 43 points more satisfied than they were in 2008.
  • Traditional cellphone owners are less happy: Their satisfaction is down 6 points from last April, " likely as a result, according to J.D. Power, "of heightened awareness among traditional mobile phone owners of advanced features available on smartphones."

The smartphone survey was conducted between January and June 2009 among  3,221 smartphone owners who have used their current mobile phone for less than two years.

In a separate survey of 12,595 traditional mobile phone owners, LG was No. 1
