Google has just announced that the Nexus S, their premiere Gingerbread device that launched in November of last year is getting the Ice Cream Sandwich, starting today. It’ll be a rolling release and GSM versions will receive it first — it’s possible some T-Mobile customers could start seeing it as early as today. Google says the update will be staggered over a month so if you don’t receive it today, just continue keeping an eye out for that Ice Cream Sandwich goodness.
