If I were part of large corporate security, no wild devices would be allowed. Every laptop HD needs to be crypted, mobile phones with email and corporate information access need to have forced automatic screen locking and possibility to clear device remotely (e.g. MDM client for Symbian). It's not corporates fault if certain devices can't fit to this kind of security policy. If any device can access this kind of information, company size should be close to man and a van category.
