Users of Google's free 411 service (1-800-GOOG-411), can now get maps sent straight to their phone. Once you've found your listing, just say "map it" to get a text message containing the address and a link to its location on Google Maps mobile. Users also get a link to turn-by-turn driving directions.
Since writing about the service in early April, I've become a regular user. Nine times out of 10, it works like a charm, while occasionally the voice recognition can and will fail--and when it does, it's often quite amusing.
If you're looking for a more flashy mobile mapping tool, TellMe's downloadable Java app gives you 411, maps, and directions in one slick interface. Assuming you have a data plan, it's free to use. Google's mobile offerings also link up to one another, including their mobile search, and mapping. For nondata plan types like me though, this new service is good way to cut data usage to a minimum.
