Just thought I would give everyone a little heads up of this great combo I ran across @ NexusSHacks. After you flash ROM & Kernel you will have to let it settle in for a few hours and maybe a few battery pulls before it becomes stable. Wait no more on Google to update ICS for the Nexus S as Im sure it will not be complete. This ROM/kernel has it all, face unlock, Google Wallet, etc. plus Wheatley governor (via SetCPU app) for best performance/battery life.
