I don't think anyone answered this - yes, the GPS records the route for you to map, mobile signal isn't needed for that bit.
Very good idea.
I don't want to sound like an idiot but if you only have GPS on and then get home and want to map the route does that still work even if you haven't had 3g/2g on when riding the route?
