As promised, Google has started to roll out the Android 4.0.3 Ice Cream Sandwich to all Nexus S. If you've not been offered this update, here's how to get it downloaded and installed onto your Nexus S GSM handset NOW!

  1. Download the Android 4.0.3 Ice Cream Sandwich update.

If you want you can also check to see if the download can be done over the air (OTA):

Click on the Menu button then Settings > About phone > System update.

I suggest you only do this when you have a strong WiFi signal (think about your data caps!) and your handset is fully charged.

And you're done!
