ICS OTA update (official ICS update from Google) has been released as of yesterday. Those of you on stock Gingerbread ROM should automatically be updated to the new Ice Cream Sandwich Android 4.0.3.
I got a bit curious so unrooted my Nexus S then manually installed the official ICS update. Surprisingly, I find the official ICS update missing stuff like NFC and Face Unlock, which worked fine on the ICS ROM by Brainmaster.
So what? I would advice not unrooting and installing this OTA update as it’s not much better than existing custom ICS ROMs.Need Help? Follow/add me on Google+, Facebook, or Twitter!
