I am looking to buy ps4 with 5.05 so I can jailbreak it. All the ones with 5.05 are used for $200-300. I would like to buy new. But they are $475-$550 on ebay. How can I buy that 5.05 just based on model #? I have never jailbroken ps4, saw alot of videos and bought ESP8266 to protect. Just need advice. There is someone sell new ps4 5.05 for $375 500GB, but I don't trust that local seller.
