ICS update for Samsung Galaxy S II now available in India!
How do I get the ICS?
There are two ways you can update the software, one is through the Kies system, for which you need a computer and an internet connection, and Over the Air (OTA).
But in India, right now, there is no OTA ICS update for the S2.
How do I do it with Kies?
You need to download Kies in your computer, and then register with Samsung from your phone if you have not already done it.

Once I do these, how do I download ICS?
Run Kies, connect your phone to the computer using a USB cable, and you are all set. Kies will guide you through the process.
Important: Please back up your data (Which Kies will prompt you to do anyway) before your update the software
