Despite the release of the official Android 4.0 Ice Cream Sandwich for the Google Nexus S, a lot of users would still prefer flashing custom ROMs on their phones. Custom ROMs are more enhanced and give you the freedom to mold your phone the way you want it to be. Unlike official updates, most custom ROMs also get updates faster and can be manually installed on your phone.
The CyanogenMod team has been working day and night to produce its own variety of Android 4.0 Ice Cream Sandwich via CyanogenMod 9 (CM9). The team somewhat slowed down on its progress with development because it needed more build servers. After calling out for help to the community, donations came in and the team was able to set up new build servers.
Now, the CyanogenMod team has made available new nightly builds for CyanogenMod 9 (based on Android 4.0.3) for the Nexus S, both GSM and CDMA (Nexus S 4G) variants.
In this step-by-step guide, you will learn how to install the latest nightly build of CyanogenMod 9 on your Nexus S or Nexus S 4G.
This guide is written for educational purposes only. Any damage or unexpected outcome on your phone will be your sole responsibility. Follow the steps below at your own risk.
Congratulations! You have successfully upgraded your Nexus S / Nexus S 4G to the most recent nightly build of CyanogenMod 9, which brings Android 4.0.3 Ice Cream Sandwich to your phone.

Did this a couple of days ago to get rid of the stock OS that was starting to become reliably slow. I’m glad I did. CM9 is very slick, adds features and improved performance and battery life. Worth a little work to get it on.
