No, the chapter name Chapter 15 is not an oxymoron. Yes, in its younger days, people thought of the iPhone as a personal device, meant for consumers and not for corporations. But somebody at Apple must have gotten sick of hearing, “Well, the iPhone is cool, but it’s no BlackBerry.” These days, among business people, the iPhone is actually more popular than the BlackBerry. The iPhone now has the security and compatibility features your corporate technical overlords require.

Even better, the iPhone can talk to Microsoft Exchange ActiveSync servers, staples of corporate computer departments that, among other things, keep smartphones wirelessly updated with the calendar, contacts, and email back at the office. (Yes, it sounds a lot like MobileMe or iCloud. Which is probably why Apple’s MobileMe slogan was, “Exchange for the rest of us.”)
