image4 | Download & Install Official Android 4.0.3 Ice Cream Sandwich ROM on Nexus S [Tutorial]Nexus S was the latest reference Google phone available before Galaxy Nexus became available this year very recently. Google Nexus S was released back in Dec. 2010. From a hardware perspective this phone is based on the popular Samsung Galaxy S except for the notable addition of NFC chip and also the lack of support for an SD card. Nexus S has the Samsung Exynos 3110 processor. This processor combines a 45 nm 1 GHz ARM Cortex A8 based CPU core with a PowerVR SGX 540 GPU. Nexus S supports 512 MB of internal memory. Screen is 4-inch based on popular Super AMOLED technology developed by Samsung.

Now the good news for the Nexus S owners is is the official availability of the Android 4.0.3 based Ice Cream Sandwich firmware. This was for the most part expected as Google devices were for sure going to get the ICS firmware upgrade with the highest priority. You can download it right now and then flash it from the recovery mode. Flashing of this official Ice Cream Sandwich firmware for the Nexus S is not difficult. But if you can be a bit patient this update will also be pushed through the OTA.

Anyway, here is the procedure to flash it on your Nexus S as explained in a simple manner by zephiK form XDA forums:

Using the volume key to navigate, select recovery, then use the power button to confirm
When you see the warning triangle and arrow, hold the power button and tap volume up. You’ll see a menu.
From the menu, select "apply update from /sdcard", and choose from the list.
Let it do its thing and update your system, radio, and other partitions. When finished, choose "reboot system now"
