We told you so. Now that Nokia is offering free GPS downloads to its customers, Vodafone, the planet’s largest mobile phone network operator, has decided to get with Google to develop a map system for other cell phones. The service will also include local listings in what Vodafone’s marketer Frank Rovekamp refers to as its “mass-market access to exciting services.” We don’t know if we would call it exciting. We just like the concept of not having to pay for a separate GPS device when we get lost.
