[Q] P920 Update to ICS

Hi,
I just got an old LG Optimus 3D p920 and its running Gingerbread. I am trying to update to ICS but the LG Mobile support tool keeps telling I already have the latest update available. Am I missing something or do I have to update somehow manually and if so, what is the easiest to do that?
