I just noticed when trying to edit my profile on the PS4 a new option is there. Apparently we will be able to use the PlayStation app on our phones to upload a profile picture. But the app must be on version 1.70 or later. So I am assuming that when the PS4 FW update goes live there will be one for the mobile app as well. I hope this update will give it "push notifications" and the ability to rotate the screen as well.
