When it comes to a consumer oriented smart phone, the iPhone is right up there at the top of the list along with your favorite Blackberry and other phones. However, until recently, the iPhone hasn’t really been noticed nor used as a business oriented phone. With recent updates including Exchange and other business features, this has changed. So much so, in fact, that J.D. Power and Associates has found Apple’s iPhone to be ranked #1 in business user satisfaction in their latest survey of 1,388 smart phone users.

It’s clear for everyone who follows the iPhone, that Apple is interested in the enterprise environment. Since the iPhone SDK press event on March 6th, Apple made it clear they wanted to be a mayor player in the business of corporative mobile computing.

Apple claims to have the best phone for business ever, but we all know how good they are on making up convincing lines for us to consume. The iPhone, so far, has great features that makes it a potential contender in the enterprise arena, but, according to Gartner, after three weeks of testing and reviewing the 3G version of the phone in large businesses, the device can be supported by IT shops, but only for a narrow set of uses such as voice, e-mail, web browsing and storage of personal information. They claim some security issues as a reason for the limited use cases.

Even though the phone could not be entirely mature for the enterprise yet, some big players are betting on Apple’s device now. They know Apple, so they also know the Cupertino-based company does take its goals seriously, and they’ll probably overcome today’s limitation in the near future.

The iPhone 3G was such a big hit that there were lines for the product even for a few days after it came out. This was bound to bring shortages, and it did. In fact, Piper Jaffray & Co. analyst Gene Munster says, “I bet we’ll see these problems for another two to four weeks. Early demand has been more than they expected [because] they knocked it out of the park on the first weekend.” He may be on to something as Apple’s stock website is still showing low amounts in most places.

Mr. Munster says this low stock could be from unexpected, sustained demand for the iPhone, as last year there was only a large initial demand. “This is a more sustained outage, and the demand seems to be sustained,” he said. Furthermore, he points out that this year the iPhone was launched world wide, meaning less stock for the United States.
