First of all: where can I find a new unopened 2000 model vita that will have < 3.60 firmware? Is it still possible to buy a new one on amazon and it'll be low firmware? Reason I want 2000 model is due to the 1000 model screens shitting out on you after awhile. Secondly: Is it possible to put a 1000 model motherboard inside of 2000 model system or are they incompatible? Because I did find a cheap 1000 mobo that has < 3.60 firmware on it. Any help will appreciated! p.s. I don't want a ps tv because I'm always playing my games on the go.
