User are excited beyond doubt, the one’s that just received the OTA, and the one’s in wait, but waiting can be annoying, and we’re sure they’re already out there looking for a manual way to update the Nexus S to the official ICS. Well there is a way, and it’s easy. Looks like Google is holding onto it’s trend to update it’s Google phones before anyone else does, so if you have a Nexus S and have not received the OTA yet, for reasons that could be a rooted device, custom ROM or more, here’s the manual method.

Update: AT&T Nexus S is not supported! Only T-Mobile and Retail versions of the Nexus S GSM are supported with this update for now.

The update is for the GSM version of the Nexus S, not the CDMA one. Please note that if you are rooted or even running a rooted stock ROM, this update may not work for you. It is advised that you to revert to a completely stock Gingerbread ROM on the device and then proceed with flashing the update.
