One of biggest stories behind the release of the iPhone 3G -- and the iPhone 2.0 firmware update for first-generation iPhones -- was the inclusion of features designed for use in business environments. While many analysts and enterprise users have argued in recent weeks about whether the iPhone can replace Research In Motion's BlackBerry as the prevailing smart phone for business, little has been said about the tools and processes that Apple offers systems administrators to actually deploy and manage iPhones at work.

In this three-part series, I'll look at three areas that make up the IT side of enterprise iPhone deployment: the activation, configuration and deployment process; how the iPhone is managed in an Exchange environment (including tips for some early adopters); and the options for developing and deploying in-house iPhone applications.

Here I offer advice on how best to activate, configure and deploy the iPhone. Parts 2 and 3 will be posted during the next month.

Activation and iTunes
One of the first steps in deploying the iPhone in any environment is the activation process. This involves both the purchase and business account setup, which is done in concert with AT&T in the U.S. or with other carriers in other countries where the iPhone is sold. Working with a carrier directly makes sense for developing necessary business plans, and it's required for any business iPhone activation, whether you're from a mom-and-pop operation or a big company.

As with any GSM smart phone, activation requires associating a SIM card with a business account and a specific phone number. This is handled by the carrier, which may provide already-active SIM cards (much like the in-store activation for consumers), or you may need to activate the iPhone after inserting the SIM card and before deployment.

The specific route you take will depend on both the carrier and whether you're re-using existing SIM cards. In general, assume that you will need iTunes to activate the iPhone, particularly if you're buying more than a handful.

Note: With the iPod Touch 2.0 update, the iPod Touch can offer several of the iPhone's enterprise features, although it cannot make or receive calls and needs Wi-Fi access for any data service. The iPod Touch is also activated with iTunes.

Although iTunes should be considered an activation requirement, it's not required for enterprise functionality. Once activated, an iPhone can be configured and used without iTunes, allowing users access to many of the iPhone's data features such as Web browsing, e-mail and other Exchange features -- including calendars and the Global Address List -- and applications. They can also send and receive calls. Without iTunes, users will not, however, be able to sync music, video, photos or Web browser bookmarks.

That means you have two major options when it comes to activating and deploying iPhones: You can manage the activation within your IT department, where all iPhones are activated with a limited number of computers using iTunes and then distributed to
