Hello, I got a question: have an Xperia Z and on the title screen I got this Sony Select app, it is there since I got the phone, but in some pictures of Xperia Zs on the Internet I saw that there is a Playstation Mobile app instead of Sony Select on this title screen, but I do not even have this app in my phone, not yet on my title screen. So, I want to know, why are some Xperia Zs shown with Sony Select app and the others with Playstation Mobile app as a pre-installed 'essential' equipment of the phone. I know, its quite a banality, but I would really like to know the matter... Thanks
