Originally, last year, it came with Android 2.3. But it could be that later models came with a higher version of Android, and it could be that the previous owner updated it. So the only one who can actually answer the question what version it is currently using is you.

Hi again,
As I purchased my Sony Xperia S second hand and said to be 7 months old, I would like to know what Operating System it is currently using and if I can update it please?
Thanks,
Phil.
