After following three enterprise-level companies attempts at adding the iPhone to their corporate mix, Forrester Research concluded that Apple's combination iPod and smartphone makes for a nice fit in big business. Kraft Foods, Oracle, and Amylin Pharmaceuticals all had good experiences when adding the iPhone to their technology pools, according to Computerworld.

Analyst Ted Schadler commented in the Forrester report, "The iPhone's intuitive interface, superior browsing experience, and rapidly evolving developer tool kit make content-centric applications far more appealing on an iPhone than on a BlackBerry or Windows Mobile device. While BlackBerry is still the email and calendaring winner, iPhone devotees do make the shift to typing on glass."

There were several reasons why the iPhone worked out well in the three companies, such as they include a full Web browser instead of a stripped down mobile browsing app, they made collaboration easier, users were able to help each other instead of always relying on IT support, the iPhone can cost less to use compared to other smartphones, and employees like the iPhone and appreciate the freedom to choose the device that works best for them.

Amylin Pharmaceutical senior IT director, Todd Stewart, said the iPhone has become the company's new enterprise notebook device, and "is easier to support than other mobile platforms."

Despite a few limitations, like limited Exchange and VPN support compared to the BlackBerry, the iPhone looks to be holding its own in the corporate world -- at least with some companies. Once iPhone Software 3.0 ships, however, Apple may be able to grab even more of the enterprise market since the iPhone will gain even more competitive features, all without costing current customers anything.
