It is time to ask the age-old question: Are our cellphones ready to replace standalone GPS units. Sure we’ve all done a little work with cellphone mapping services and we’ve all mucked about with Google Maps while driving (which is very dangerous). But are cellphones and iPhones in particular ready to knock the old GPS box off of the dashboard?

To paraphrase Molly Bloom in Ulysees, “yes to say yes my mountain flower and first I put my arms around him yes and drew him down to me and I think you can replace your GPS device with an iPhone and software like Navigon’s Mobile Navigator for iPhone are making it much simpler yes I will Yes.”
