The Nexus S 4G from Google has been around for some time already, and it is about time it is on the receiving end of the Android 4.0.4 Ice Cream Sandwich update. Well, I guess owners of the Nexus S 4G should be pleased to hear that BriefMobile managed to get some hands on time with the files necessary for the upcoming Android 4.0.4 Ice Cream Sandwich OTA (Over The Air) update. Needless to say, before you make that particular upgrade, just ensure you have performed all the necessary backup moves beforehand. After all, you can never quite tell just when Murphy will strike, right?
