This Yahoo! news story says that TapRoot Systems has (will have?) some new software called “WalkingHotSpot”. I haven’t found anything on TapRoot’s website yet but the article says it’ll support Windows Mobile and Symbian 60 phones. The demo version, which is to be free to individuals, supports one WiFi connection at a time. Keep your eye on this, especially if you keep forgetting your USB cable like I do.
