Corporate configured iOS devices that are centrally managed are not as secure as mixture's post might make you believe. In fact centrally managed iOS devices allow the administrator pretty much unrestricted access to most data and all apps on that device. Easiest to be done via apple servers, but there are third party companies that do it for you if you want. If you use devices like that in your company better have a CLA about its use and the access the company has to it.
