Here the  first method: "Fake Serial"
First thing you do call psn (800-345-7669) after that keep hitting 2 on your dial pad. Once you get a agent you can do one of the two ways. 1.ask for someone who speaks spanish(they are easier to SE) 2.Tell them your account got hacked, ps3 got restored make up a reason. After that they will ask for your psn,name,and email. Give them the psn name you want to jack , then make up a fake name and email. The agent would say im sorry but the email is not matching to the account , do you have the original console you created your account? This is where you say Yes and give them a fake serial (ex: cg162174830-cech-2001a) the serial starts with 2 letters after that is 9 numbers. Once you give them that you have to pray they don't check the serial number,Most of them do check but some of the  agents are lazy and don't check it. If they don't check it they would ask can i get a email that is not used on playstation or can i get the new email you want to put on this account and it not used on any playstation account. This is where you give them a new email that you want them to change it too. and now there your OG account ....... This is the main method most people use to get USA accounts. it will take more then one try unless your lucky on your first.
