I don't believe you or I could access the source code for the radio (phone) app on Android, so anything the NSA wanted to hide, it could hide there.

Total ignorance. Apple OS X is a fully featured and open trademarked UNIX operating system. You REALLY ADONT KNOW WHAT YOU ARE TALKING ABOUT. Every Mac user is either a couple of keystrokes or clicks away from a fully functional UNIX Terminal, if they choose to use it.
