Similar to the cell tower based location tracing provided by the native app Navizon, Google has added an option called My Location. My Location is new software that is included with Google maps which works with non GPS phones. As most know the iPhone does not currently have GPS, so it fits into the category. As of right now this feature is only on the beta for the standard Mobile Google Maps. Unfortunately it is not yet on the iPhone, but I hope it will eventually be included in an update. I would love to see an integrated and reliable location finder that is authorized by Apple. As soon as the SDK appears we may have competition over these kinds of applications (Google vs. Navizon). When this occurs I will use the app that I know will be free, Google Maps. 3 cheers for simplicity, seamless integration, and free software!
