there wont be after 3.55 it was impossible to jailbreak ps3 with out flashing sony will not make the same mistake as last time unless a hardware flasher comes out for ps4 but even then theres no dump to jailbreak/downgrade ps4 so there for its impossible
i'm sure there is a way somewhere, but it's kinda pointless because although it's possible only with a hardware flasher, it's still possible.
ok, not all consoles can be downgraded to 3.55, but that's not really a big deal considering the fact that you can just go on ebay and get one that's on 3.55 or a downgrade-able console. and i do believe there will be a ps4 jailbreak eventually, because there is a lot of progress with the ps4 scene, including a developer dumping 15mb of unencrypted data. finally, sony are dumb fucks and they will make a mistake which will be fatal
