Can't you just go into settings and turn off Location Services?

THAT would actually work BETTER because the phone use other ways to
get your location.  It measures the distance to several cell towers
and it can listen in to WiFi hotspots and then use a database to
figure out where you are based on what WiFi it can hear.

As an example my Apple iPad has no built-in GPS but it still gets my
location to within a few hundred feet
