How to install Ice Cream Sandwich on the Nexus S

If like me you have a Nexus S phone on Android Gingerbread and are getting more and more impatient to when you will finally get the update notification from Google, some bad news first: Google halted the process in January as there were reports from users about battery life and few other minor issues. More than a month has gone by, and so far no updates...

Now the good news - I just installed the official ICS 4.0.3 on my Nexus S and it works and looks great! Like many of you I don't really like all this talk about rooting your phone, flashing it and other things - my fear of bricking my phone from making a mistake is just too big. However this method of installing ICS on the Nexus S could not be simpler and in 10 to 15 minutes you'll have your phone up and running! 

This was the method I followed from ZDNET (which you can see in full following this link):

1. Download the Android 4.0.3 Ice Cream Sandwich update from this link.
2. Connect your Nexus S to your computer via USB and copy update.zip to the root of your SD card (Do not drop it into a folder or this won’t work!).
3. Power down your Nexus S and power it back on while holding down the volume up button.
4. Use the volume buttons to navigate to RECOVERY mode and press the power button.
5. When you see the exclamation mark on the screen, DON’T PANIC! Press the power button followed by volume up.
6. Select the option to Update from SD card select the update zip package you downloaded earlier and press the power button to confirm.
7. The update will now install automatically. When it’s down your Nexus S will boot up into  Android 4.0.3 … enjoy!!
