I can't find Blackberry Maps on my home screen although it has been installed. After quite a bit of browsing through some Blackberry users forums on the web it turns out to be that some carrier is hiding the icon on the home screen and it can be restored by trying to reinstall Blackberry Maps. To reinstall, go to http://www.blackberry.com/devicesoftware/entry.do?code=maps. The funny thing is the install prompt will be for lbs_ribbon. Just proceed with the installation and after the installation is done, the Blackberry Maps icon should be on the home screen.
