Having "wire-tap access" and actually being able to decode the content are two different things.
All you have to do is encrypt the content before the phone encrypts it yet again. Then the government, when they decrypt your communications via wire-tap access, will only find further encrypted communications.
For those of you paranoids out there, there's message encrypting apps for that :)
