I highly doubt that it's a jailbreak, probably found some glitch to have God mode. If he did have the jailbreak I doubt he would be on Gta flaunting it.
I was Modding over 2 years on the PS3. Now i pretty happy that the PS4 isnt still jailbreaked. I really like it that Way. If u ask me they can wait with the Jailbreak a Year or more..:-) :-)
ps4 has been out for two years now lol, and people are still finding some retarded video saying that the ps4 is jailbreakable. lol atleast 5 or 10 years people calm your clit lol i bet the people with the romurs are 12 year old kids with no friends nor life
