I just bought a used Vita. I didn't really want it but the deal seemed too good to pass up. Anyways, I was looking through it and it looks like it still has some games and stuff on it. 3 Vita games and a 1 PSP game. I'm wondering if I change user accounts would the games still be useable? Side question: FW is 3.55 should I keep it there and hope for a new exploit or CFW to come out?
