Ever since the Google Nexus One was announced (and then released) last month, talks were on about its forthcoming multitouch support. We all knew that the phone was more than capable to integrate multitouch gestures. Google, however, for some reason, chose not to include it in the initial firmware that the Nexus Ones came. There was a small fix that enabled multitouch in the browser. But that was from unofficial channels.
That was then. Yesterday, Google issued a small OTA (Over The Air) update for the Nexus One that brings in multitouch support to it - apart from numerous other improvements. Multitouch has been enabled in the gallery, browser and Google Maps where now you can pinch and zoom - just like on the iPhone. Google Maps has also been updated to version 3.4 and brings with it items synchronization, search suggestions from users' personal maps history, and a very interesting "night mode" in Maps Navigation. The update also adds the Google Goggles application that was first seen in December 2009.
Under the skin, there seems to be not much of a change. We can expect another update in the near future that will help Google fix the 3G connectivity issues that many users faced initially. As for the update to arrive for on your phone, you would have to be at the mercy of your operator to have it issued for you. Of course, there is another way out where you can update manually to get this same OTA version. More on that here.
As always, if you plan to update, do take a backup of all your data. Just in case, you know.
