Yeeesh, the minute your phone connects to a tower you are giving up personal information. BTW, what do people think is the reason Google got into cell phone operating systems for in the first place? It's not because they wanted to just make our lives easier. There is a quid for that quo and most of us agree to this "something" that they harvest, every time we click that "accept terms" button at the bottom of that annoying page that seems to pop up right before we check out that coolest new web app or suttin'. Services like Last.fm, Instinctiv, and Pandora aren't "free" to use because someone wants to teach the world to sing in perfect harmony. It's because companies like Coka-Cola want you to buy more of their product and the providers of these "free" services are selling these companies on the idea that some of the information that they gather will help them do just that.
