Hey Guys, i have a few questions that im trying to find answers to concerning the Vita. I know that the Vita is not region locked, so my first question is

If i get the R3 Uncharted, i can play normally. But will i get the trophies if i am using the US PSN?

My second question is.
Can i use the US PSN shop to buy games if i am outside the US?...I am getting the US PSN card coz i know it does not work with any other credit card.

My third question is about DLC
Can i use DLC if i am using a US PSN account for a region 3 game?

Sorry if my questions are for noobs, but this is my first PS device that im using with online capabilities :-p

Thanks for the help.
