Facebook appears to be testing a new location-based feature that permits some users to identify free Wi-Fi hotspots through the social network's mobile application for the iPhone and iPad.
As reported by The Next Web, some users, myself included, are now seeing a Find Wi-Fi option in the app's side menu, between the Nearby Places and Nearby Friends options. Tapping it puts up a prompt asking to grant Facebook access to your location so it can find public Wi-Fi hotspots around you.
