you're exactly right on that, it's exactly what happened in our office.
i don't think our IT dept had any warning, it's just that suddenly, half the IT team, have the business users and a very large number of the higher management were using iPhones as our personal phones and so began to also use them to access the online Outlook web portal, forwarding emails to home accounts, storing meeting details and contacts on the phone. so the only sensible option was to implement the Good Technology solution which at least keeps all that sensitive corporate date locked and encrypted.
The point that SteveBalmer's post above overlooks is that, it doesn't matter what solution the corporation implements, if the users are going to go ahead and use their own technology regardless.
Maybe it's different in your industries, but in mine, IT Departments are cutting costs as fast as employees and so finding a secure way for users to make use of their own phones and tablets is far more preferable to spending the money buying blackberries for them all.
