From Defense Systems:
The Dell Streak 5 smart phone/small tablet computer is the first handheld device using the Android 2.2 operating system to be certified for use in the Defense Department’s secure but unclassified communications, said John Marinho, director of Dell enterprise mobility solutions.
Although the Streak 5 is no longer available commercially, Dell is supplying it to DOD because the military likes the form factor, Marinho said. However, he added that the same capabilities and service can be delivered to other platforms running on Android.
Only DoD would approve a device no longer commercially available.
