mobile_app: fix some configuration r/w bugs

Previous patch did not fixed one more bug: old code reads GPSD port with a
colon.
I have fixed it. Final patch version:

Hi Vadim,

thanks for your patch, but..

a) if you remove code, remove it for good, not just comment it out

b) the double-equals will not cause an assignment. I don't think you
   tested this code...
