Just tried using iWant to find the name of an Indian restaurant near my office and I saw lots of addresses on El Camino Real. I've never heard of an El Camino Real in Northern Virginia, but I know that this is a main drag in Silicon Valley. I switched to Google Maps and clicked on the current location buton in the lower left hand corner and it thinks that I'm on US 101 (or "the 101" as they like to say out West) near San Carlos, CA. But I'm not. I'm in Northern Virginia. I haven't been to Silicon Valley since at least six months before I got my iPhone 3G. Also, this location is apparently based only on cell tower information -- I don't have the little blue dot which the GPS provides.
