I bought a Samsung Galaxy S2 10 days ago in order to enter into the smartphone world. After a day or so playing around I decided to upgrade the operating system in order to be ahead on the arena.
I was looking the different ways to perform the task watching videos, reading, etc but nobody mentioned the simplest one.

1) Download Samsung Kies software that allows you to manage all the typical smartphone tasks like contact lists, videos, pictures,etc.

2) Connect your Galaxy S2.

3) Check for updates.

4) Accept to upgrade your operating system.

5) 10 minutes later: eureka!...job done.

6) Enjoy and play a lot to take advantage of the new Android powerful operating system.

Here you have the whole process in pictures:
