Finally, Google has released an over-the-air update enabling multitouch, Google Goggles,  a new version of Google Maps and some 3G fixes. Users will receive a message on their phone’s notification bar, then just download and install it.

Google Maps: the Maps application with be updated to a new version, Google Maps 3.4, which will include:
Starred items synchronized with maps.google.com – access your favorite places from your phone or computer
