Did you read the thread you first posted in? BB Maps not found, Help please
If your carrier isn't blocking BB Maps, go back to the original OS that came with the device. If they are, then try Google Maps or one of the other map apps for the BB. See the yellow sticky at the top of the GPS & Maps section for more info.
You can also use the SEARCH feature and Google Search for more info.
