is facebook apps preinstalled in Sony xperia s

I about to buy Sony xperia s so I want to ask you that is facebook apps preinstalled in xperia s because I am addicted to facebook a lot and I chat on facebook whole day with my friends. There was no facebook apps preinstalled in my LG cookie fresh I am using currently so I installed it by downloading from net. So I just want to ask you guys that is face preinstalled in xperia s if not than can I install facebook apps in it?

Yes, it’s facebook is preinstalled in xperia s, and if it is not preinstalled then it is obvious that you can install apps like facebook in this android phone which support thousand of apps.
