Because it takes tens of millions of dollars to replicate the functionality of the Ipod-Iphone. Chinese do it in a completely different way, using prefabricated components. Secret services can not use prefabricated Chinese components because those need to be audited and that cost millions too. So using already made American companies components' is the obvious solution. It just cost hundreds of thousands of dollars.
