The folks from MapQuest — remember them? — have released a version of their site optimized for the iPhone and iPod touch; visiting mapquest.com from one of these gadgets will automatically load the appropriate version. I’m afraid I have to agree with Gruber: “[N]o matter how good their maps and directions, it seems hard to compete with the built-in (Google) Maps app with a web app that doesn’t have access to CoreLocation.” And in the usual MapQuest fashion, the first page you’re presented with is a search box, not a map.
