Google have released Google Maps for mobile 4.1, which has a lot of new features.
My favourite new feature is the Maps live wallpaper. If you press the “Menu” button from your home screen and select Wallpaper > Live wallpapers > Maps you can turn your home screen into a live updating Google Map (only available for Android 2.1+ phones).
Google have also updated the Google Maps for mobile search results page. The results are no longer shown with tabs but with buttons. The buttons allow you to view the searched place on a map, get directions, call it, or see it with Street View.
On Latitude phones you can also add the Latitude widget to a home screen panel.
