As it stands now, U.S. soldiers aren’t allowed to send classified data from their smartphones, which makes sense to me. Only approved, secured devices can be used to transmit data of value. That should change soon, hopefully, as the new phones start rolling in, first to a few soldiers, then federal agencies and maybe contractors. Users will be able to install new apps on the phone, but the phone will have strict limitations as to what information those apps can access.
The U.S. won’t be building the phones themselves due to cost reasons. They’ll be buying commercially available phones and reflashing them with their software. They had wanted to use iOS, but unsurprisingly, Apple didn’t like the idea of sharing their source.
The project is being funded by DARPA, who also funded Apple’s Siri initially, so hopefully whatever the government comes up with will eventually be made commercial. I don’t want anybody intercepting my saucy texts.
