As far as I know, FoursquareX is using CoreLocation API of Mac, however sometimes we're on wifi or we're on a wifi location (such as somebody's home) on which no other access points around available and unable to detect location using MAC address of wireless access points – or we just use desktop client. As an enhancement, I think a manual location setting should be implemented and this choice should be given to the user. I'm not sure whether this is illegal on foursquare but I'm using fake location simulator on Android since in my country, carrier geolocation data is not accurate. And most of the time I'm at my home or office using Ethernet and do not want to use my phone while my hands on keyboard. It would be nice.
