When the iPhone (News - Alert) was introduced, and even to a large extent right now, people saw it more as a communications tool used for pleasure than for business. If you are a business or a business person, BlackBerry (News - Alert) was probably the way to go, according to conventional wisdom.

But that's not necessarily the case, for a number of reasons. That includes the fact that, for many people, the line between work and home life is blurring, as work hours expand and remote working has become commonplace. Plus, many folks who have become accustomed to using Apple (News - Alert) interfaces for other uses might want to enjoy the same experience for their work lives.

Indeed, according to one report, a British bank called Standard Chartered recently made the decision to switch out its BlackBerry fleet with an iPhone solution. The group-wide initiative could have thousands of bankers move to the Apple iPhone, according to the story.

That, of course, is not music to Research in Motion's (News - Alert) ears. The BlackBerry company owns the No. 1 place in the U.S. smartphone market, with 36 percent share. But the onslaught of new smartphones, including the iPhone, is challenging RIM now more than ever.

As TMCnet reports, the CFI Group's smartphone satisfaction study -- based on surveys of more than 1,000 smartphone users - indicates the iPhone is the leader in customer satisfaction, scoring 83 on a 100-point scale. And, the CFI Group study goes on to say that smartphones that traditionally have been popular among business users, like Research in Motion's BlackBerry and Palm's Treo, trail significantly in customer satisfaction.

"Consumers clearly want to do more with their smartphone[s], and if you give it to them they will buy it and use it," says Doug Helmreich, program director with CFI Group. "The good news is that there's an opportunity to move customers into smartphones. The bad news is that nobody really knows if the networks will be able to handle the stressthat will come with data-intensive usage typical of the new wave of smartphone users."
