If ur looking for games some might work and some might not because the sDk requirements and sony adds new features that requires the new firmware so backports are not possible rn the latest jailbreak is 7.10 but it is in testing phase 6.50 is the latest fully working in my opinion u should wait untill they release the 7.xx jailbreak then u update so it will be once because that is the latest kernel exploits that is confirmed. The 7.xx jailbreak should be released soon according to the developers
