Hitchhiker 0.1 is a free PocketPC utility from the same folks who made WiFiGraph. It will help you connect to WiFi hotspots that it has located in your vicinity. All you have to do to make this happen is click on ‘Connect’! Hitchiker will manage the reconfiguration of system settings for optimal connection speed, perform Internet connectivity tests automatically, report if the connection requires login and it will keep a connection history (with successful connection ratio).
It does require Windows Mobile 2003 as well as WiFi connectivity.
Best of all, Hitchhiker is a free download.
