As unpopular a suggestion as this may be, Blackberry's are very secure particularly if you enable some of the more advanced security features such as secure memory and full device encryption. A lot of research has been undertaken at my University into this recently and very little progress has been made.

The obvious downside is that the App eco system is still very poor compared to both iOS and Android and the UI leaves a lot to be desired. It depends really on whether you favour security over usability.
