Just point your mobile browser to http://www.google.com/gmm/winm and it will download a .cab file. Install it and go! It’s awesome… and includes satellite imagery, street maps, zoom in/out features (hit I to zoom In, O to zoom Out), search and direction features. It’s super fast too!
This is a must-have app, and it’s free thanks to Google. Go check it out! Here’s a screen shot I just made on my phone after searching for “space needle” and nothing else specific. It came right up, and all I had to do was to zoom in a few times.
