Nexus S and Nexus One owners can expect an update to Android 2.3.3 to hit their devices soon. Google just tweeted that the OTA update is already rolling out, but users should be patient since it may take a few weeks for the process to complete. This marks the first appearance of Android Gingerbread on the aging Nexus One, showing the benefits that come with purchasing a Google flagship phone. On the other hand, we’re curious to see how long the Nexus S will receive such treatment from Google, seeing how its specs are already yesterday’s news after the unveiling of some impressive new smartphones at Mobile World Congress this year. Android 2.3.3 is a minor update for Nexus S users, as it includes bug fixes and the ability to write (not just read) NFC tags.
