It was simple and clear in the old days of BlackBerry services-you used your BlackBerry for work, and that was it. Now there are many device choices, from iOS-based phones and tablets and Android handhelds to Research in Motion's Playbook and many others.

It's important to decide exactly what you mean when you say "bring your own device." Should you really be saying, bring your own iPhone but not your own Android phone? Bring your own iPad but no other phones or tablets? Make it clear to employees who are interested in BYOD which devices you will support%mdash;in addition to whatever corporate-issued devices you continue to deploy-and which you won't.

Users tend to resist having passwords or lock screens on their personal devices. They see them as a hurdle to convenient access to the content and functions of their device. However, this is not a valid complaint-there is simply too much sensitive information to which phones connected to your corporate systems have access to allow unfettered swipe-and-go operation of these phones.
