Some GPS receivers like new iPhones combine celltower location, GPS, GLONASS, WiFi, all simultaneously. On my iPhone I get a relatively accurate fix even in the basement of my residential house. SoBi uses a mobile-phone GPS receiver so it may be doing the same more-indoor-friendly 'sensitive GPS' fix.

Even when GPS lock is lost, it can still probably use WiFi/celltower location to get an approximate fix, or at least report itself as having lost GPS lock, and send last good GPS fix.
