I recently moved across town and set up a new internet connect with a new modem but the same wireless router. When I'm at home and connect to WiFi, Safair works fine, but when I use the GPS it shows my location as my old house. Does the IP address need to be reset on my iPhone? If so, how do you it? It's not really that big of a deal unless I'm planing on routing a trip from Current Location. Any suggestions?
