Google will start pushing out the newest version of Google Android 2.3 Gingerbread to the Nexus One and Nexus S smartphones in the coming weeks. But you may not have to wait that long to get your hands on Google Android 2.3.4, because the source code for the operating system has already been released.
All we know about the update right now is that it’s designed to fix some bugs in the Nexus One and add support for voice and video chat to Google Talk on the Nexus S.
I suspect custom ROM developers will be able to incorporate some of those features into software for those phones and others pretty quickly.
