How to Use BlackBerry Curve 8330 and Google Maps
Once Google Maps is loaded, it will show your location on a map noted as a blue dot. It should also show how accurate the location information should be. On my BlackBerry Curve 8330, it fluctuated between a 10 to 50 meter accuracy while indoors.
To zoom in on the map, press the letter I (-) key and to zoom out press the letter O (+) key. You'd think the keys would be the other way around like pressing the plus sign to zoom in, but it's backwards. As you zoom in, you will see more detail like street names.
To view your options, press the dotted BB key to the right of the scroll ball and it will pull up a menu of choices. You can search the map, view the actual satellite imagery of your location, and more. Just know that it's a lot slower in satellite view because of all the image data being transferred. You can also select Layers to get more information on the map, such as Wikipedia entry information for nearby locations.
If you want to get directions to somewhere based on your current location, choose Select Destination and either enter the address or visually locate it on the map. Google Maps will then tell you how to get there and how long it will take for you to arrive, plus you can view the map to show your progress. It's great for road trips to give you an idea of when you'll reach your destination. If your BlackBerry screensaver kicks on while looking at the map, just press the spacebar to bring it back up.
