Hi, I have 2 ps vita . One of them is on firmware 2.2 I think and the other is on 3.55. I didn't use them till now. I want to update only one of them to the latest firmware to access psn store and download stuff while keeping the other waiting for future ps vita hacking (psp iso and hopefully ps vita). I don't want to use PS3 to hack or update my ps vita because my ps3 is hacked and I don't want to risk linking my ps3 to psn or internet. .First question :Which one to update to latest firmware 3.61 for psn access . I heard that firmware 3.55 is not completely hackable so should I update it and leave the 2.2 one for hacking . Or they are both hackable for psp games ? Second question : Later , can I use only my pc to update the other vita to 3.60 for example ?
