Earlier today Google released a version of Google Maps called local for mobile that runs on most Java-enabled mobile phones . I was able to easily download the app onto my Nokia 6620 and start making use of it. The experience was much more seamless when I finally found the setting in Nokia’s AppManager to not prompt me every time the app wanted to connect to the web (which was a lot).
One downside that I found is that there is no apparent way to ‘bookmark’ locations (say, your home, or place of business) to make it easier to zoom to places where you commonly find yourself. For that matter, bookmarking would make it easier to get directions though the service because you would commonly want directions to/from your home or place of work. Bookmarking would be a great addition, as I find that anything that keeps keying and mousing to a minimum on a mobile device makes that app/service all the more valuable.
I found the Google offering much snappier (speed-wise) than the previous app that I was using on my 6620 called MGMaps. MGMaps basically served the same function in delivering Google Maps to mobile devices. It may be that MGMaps may go away altogether now that Google has introduced its own mobile application.
