Google announced today that the latest version of Google Maps for mobile with Street View is now available for Windows Mobile and Nokia S60 devices. Street View is already available for Android, BlackBerry, and iPhone devices so this is just catch up for the former two mobile operating systems.
Aside from Street View, the new Google Maps for mobile version 2.3 comes with some other new features. These include walking directions (in addition to driving and public transit), transit alerts from participating public transportation authorities, a more responsive user interface, and more.
You can get the latest version of Google Maps for mobile by visiting http://www.google.com/gmm on your mobile phone (or from a desktop to send yourself the link).
