Slideshow: Forget iPhone 3G S: Eight Great New iPhone Alternatives

For some time now, Apple's offered its free iPhone Configuration Utility for Windows and Mac that lets IT set up and install configuration profiles on iPhones in BlackBerry-like breadth. But it doesn't provide the over-the-air reach, the granularity of control, or the visibility that BlackBerry Enterprise Server offers. Lacking these key needs of larger businesses, iPhone Configuration Utility has been dismissed as a toy application.

But last week, Apple shipped the iPhone 3.0 OS that adds improved support for Microsoft Exchange ActiveSync policies, and it made available the 2.0 version of its iPhone Configuration Utility, with significant new management and security capabilities. Can IT now manage the iPhone in the manner of the BlackBerry and Windows Mobile device?

To answer that question, the InfoWorld Test Center has been testing both the version 2.0 iPhone Configuration Utility and Exchange ActiveSync as approaches to managing iPhones to see how well they really work, and what types of IT and businesses can effectively use them -- and which cannot.

The short answer: Each tool has important capabilities that the other lacks. For managing our fleet of iPhones (and iPod Touches), we'd prefer to use them in combination. For shops not running Exchange, managing iPhones with the iPhone Configuration Utility alone has one critical drawback: Should the phone be lost or stolen, an administrator cannot initiate a remote wipe of the phone's data, or receive confirmation that a remote wipe occurred. But we found that managing iPhones via Exchange is no substitute for using the iPhone Configuration Utility.

iPhone Configuration Utility 2.0: Powerful but not scalable Apple's free iPhone Configuration Utility, boosted to a 2.0 version when iPhone 3.0 OS was released, has a rich array of policy controls that give IT great authority over iPhones and iPod Touches. The UI is easy to use, with various capabilities broken into "payload" sets that you switch among and configure for a given configuration profile. And they really do work, strictly enforcing their rules on the client devices.
