Cincinnati Bell’s Samsung Nexus S is among the handsets that will be receiving the Google Ice Cream Sandwich 4.0.3 update. The updates will follow Google’s OTA schedule which will be pushed out through January 2012. Please keep in mind the update requires Android 2.3.6 to work properly and will NOT work if the device hasn’t been updated from Android 2.3.4 software. Contact your local Cincinnati Bell Wireless store for information relating to updating your Nexus S to Android 2.3.6.
Even though didn’t give a specific date in January, it is still likely that an update might start hitting your devices sooner. It all comes down to what Google has set up and scheduled for the device. You can bet there will be an update in the coming weeks at least. As the statement also mentions, if you are looking forward to the ICS update, you better make sure you are currently on Android 2.3.6 first or you will miss out entirely.
