I didn't reply to this bit, sorry.

Yes, this would be possible.

I think you'll find they don't use the same clock though - the GPS clock 
has to be much more accurate and is run off the atomic clocks in the 
satellite while the audio clock (set in the phone) is probably set by 
you on the phone settings, and will probably drift apart over time.

It is always possible that the track recorder will use the device clock 
not the GPS clock to record its waypoints, in which case they will be in 
sync of course.
