ok so i hate my online name, so i want to make a new PSN account. i know i can transfer my save data no problem and i know i have to earn all of my trophies back. here is what im really getting at, if i were to transfer over a game such as battlefield bad company 2 will i then be unable to earn my online achievements for something like unlocking a certain gun or for ranking up? also would i need a new VIP code?

this is a make or break deal for me because i play BF:BC2 like crazy
