Hey Gordo,long time buddy. Interesting question you asked. There is not much to be done to protect yourself from the government snooping. However,many people are opting to use vpn's,and use more secure messaging systems protocols.
What people need to realize is that you have more personal data in your phone usage that your computer.
The use of vpn's are ok if you're using an off shore with no logs kept. but even tho they state they don't,you can never be sure they do keep logs.
A good example is "hidemyass" proxy vpn. They kept logs even for paying subscribers. That's how the FBI was able to catch the member of anonymous "Sabu".
Like you i have nothing to hide,so they can look in my privacy lol.
