We covered the recently released AOSP ROM for the Nexus S running on Android 4.0 and today we’ll cover briefly on how you can install it on your Nexus S. The ROM is almost perfect for daily use, the only issue being the broken camcorder, tethering and data usage limit. However things like WiFi, hardware acceleration, GPS, camera, face unlock are working perfectly fine.

You will need a rooted phone for this to work.

Rooting voids your warranty. Not following the instructions carefully might result in a bricked phone. Proceed at your own risk!
