There was an article in CSO that listed the poll responses from CSOs, CISOs and security managers when asked what employee owned devices were allowed to access their company email. iPhone/iPad and Blackberry were both the most allowed at 78% with Android following at 46%, which is a pretty significant difference between the two big players. The least supported devices were Windows Phone 7 (18%) and Mobile (15%), with Symbian bringing up the rear at a mere 6%. Sorry Nokia. About 1 in 5 responded didn't allow ANY BYOD use.
