Google Nexus S Gets Android 2.3.1 Update Over The Air: The Smallest Update Ever
Google has quietly released an update for its newly launched Nexus S smartphone that is an Over-The-Air update. This includes some important bug fixes as well as the latest update of Google Maps.
The 2.3.1 update only weighs 1.9MB. Hence, one of the smallest updates ever released.
This allows the Nexus S to update from GRH55 TO GRH78. Here is a context of the text listed there regarding the update:
Nexus S owners who haven’t received the update yet, try the force checkin method that may fetch you this update. Just open the dialer and feed in *#*#checkin#*#* code to dial. Once it succeeds, you should get the software update notification on the top of your screen.
Previously, just on the release date, many users on the XDA Developers forums had rooted the Nexus S, just after a few hours after the phone was launched.
