Android 2.3.4 over the coming weeks, but Google earned a +1 from eager fans and devs hoping to get the extra Google Talk functionality sooner. Instead of hopelessly checking for updates until the time is right, the Powers That Be are now offering the upgrade as a manual download to anyone who is already running 2.3.3 on the i9020T (the AWS-equipped model). We urge you to proceed with caution here and double-check that your phone is compatible, since those are the two requirements for the download to install properly. We've happily bumped one of our devices up to 2.3.4 this way without any sweat or tears, so we hope it will be a smooth experience for others as well. If you choose to be adventurous and update your Nexus S, click the source link below to download the necessary ZIP file.
