Good luck telling corporate users that just a few years after you've allowed iPhones and/or Android phones as their devices on your exchange server, you're going to ban them. It was easier for things like this to happen back when everyone was carrying a company-issue blackberry (because blackberries were too expensive for most consumers.) These days, companies are increasingly just letting their employees connect personal devices onto their exchange servers (with policy management) and enjoying the savings from not having to pay for the device, data, or both. I can't see either group (companies and employees) being happy about reversing this trend.
