People who apply for the v5.5 test can choose to automatically be enrolled in future firmware betas without having to register every time; if they do so, theyíll receive an exclusive PlayStation Network avatar, a blue shield bearing the PlayStation buttons.Unlike Microsoft, which runs a preview initiative called the Xbox Insider Program, Sony does not have an ongoing system for customers to test upcoming system software updates. Sony seems to be conducting beta testing only for what it deems major firmware revisions, although the last big one, v5.0, was kind of a bust.
