Cell phones and the Internet are nothing but "tools". The only matter of trust we should have with regard to phones and Internet access is that they will work.
A fork for example is neither good or bad. It can be used to eat a garden salad or it can be used to eat a large slice of double fudge chocolate cake. The real issue is do you trust (the person) using the tool? If the answer is (no) then you need to move on and find someone you do trust.
