You read that right. Currently, the mobile security of the BlackBerry makes it the only DOD approved mobile device.
The pentagon is currently developing strategies and making contingency plans in the event that the financial woes BlackBerry is experiencing means that the DOD cannot get devices from them anymore.
This is disturbing to me. While my phone (Android OS) does not contain state department secrets, I would like to think it is secure to hold such sensitive information. This also means our tablets do not have security capabilities that the DOD deems secure enough. Hopefully the pressure for Apple and Android to develop such secure devices will allow their consumers to have access to such secure devices in the future.
