Much time has passed, since the release of PS Vita and there is no real software jailbreak or hack outhere. Maybe I'm wrong because I am not a professional at this, I think it's time to concentrate at hardware hack, there is plenty of space inside the ps vita for modchip or create a flashcard like r4 on nintendo consoles. Also all PS Vita 1000'th series has useless videoport, that in thieory can be used, again I am not a proffesional and I can be wrong. Hackers need to concetrate on finding holes in PS Vita Cards or PS Vita games security. Maybe try to find the way to flash game directly in-to the Vita game memory chip, which is contain game, like it was back in 90's on NES.
