Uncharted 2 Beta code trade on the Ps3?

I'm Looking for an uncharted 2 beta code. If you have downloaded it on to your system, i can go on your account and i can download it from ur downloaded list. If i go on your account, you can go on mine and you can get my Final Fantasy 7, Resident Evil 1, Pain, Burnout Paridise and many more. All of my friends have the beta and they all want me to play with them and i am in need for a code. Please help me :)
