(adsbygoogle = window.adsbygoogle || []).push({}); I used to play on my ps4 but then switched to pc and I don't know anything about ps4 jailbreaks and stuff. I was just wondering if there was any "webkit" or jailbreak for 4.55 and how I would do it.

I mean qwerty's webkit works on 4.5X, but hasn't ran anything to actually do it. So, on the low, I'd say no.

Actually every firmware is jailbreakable, but no one released one so far.
You/We have to wait some weeks/months, but i'm confident that someone will release soon....
