Pentagon Approves Android Devices at Department of Defense

For many years BlackBerry has been the only device approved for use at Department of Defense (DoD) mainly due to the security features available in Blackberry. Recently DoD, for the first time, approved the use of Android devices by its staff. Currently the only device approved for use is the Dell Venue running Android 2.2.

Apple's iPhones and iPads are not far behind. iOS devices are also being tested at DoD. I wonder once iOS devices are approved and more Android devices added to the list of approved phones how many staff members will jump the BlackBerry ship?!?!
