I pre-ordered World of Final Fantasy which will most likely need 3.55 when it releases anyway. Even if I lose TN-V it's not a big deal as I probably won't use it much anyway, it's just nice to have. There will always be a new game to exploit, and no one's doing much with rejuvenate anyway.I see. Just a heads up though, if you update to 3.55 for online/psn access and sony released a firmware update past 3.55, updating to it could have a risk of breaking the tn-v hack you have installed. It is a constant struggle for ps vita owners of do you want psp hacks, and in your case since you are on a low firmware, native ps vita hacks like rejuvenate or future native ps vita hacks, or update to have online and psn shop access.
