PSN ID in Sig??

I just got my PS3 a couple of days ago and I can't figure out where to sign up or how to get my PSN ID into my sig. I have gone onto playstation.com (us) but I want to use the account I made on my PS3 and not have to make a new one. Cans omeone tell me how to do this???

like a trophy card?

playfire.com

uk.playstation.net

go to ps3trophycard.com, and you'll get the code after you enter your psn name, and put that code into your sig

thanks

So does ps3tropheycard.com NOT update at all?
