Go into a random defense contractor office and (assuming you can get in to do this) ask them how many of their iPhones are managed by the company. The percentage who say theirs are will be close to 0%. Most are personal devices, and they use them to call into meetings with DOD officials all the time with no special precautions taken.

Wym "backed by"? This makes no sense. I am a contractor, use an iphone, and never connect it to govcloud.
