Even though you can install the (unofficial) new Gallery app with multitouch on the Motorola DROID, it appears that Google has got one better. Today on the Android Market you can install the newest version (3.4.0) of Google Maps, which also comes with multitouch built-in. As this is the first official Google app to support multitouch for the DROID, we were eager to try it out. After the download and installation were complete, we loaded it right up and could easily zoom in and out by using two fingers (pinch-and-zoom), but you can still zoom by double-tap and by using the magnifier icons on the bottom-right corner. Now it would be nice if Google could provide a browser update with multitouch for the DROID.
