YES i know there is a big faq in steam, but my problem is this one.

I just bought portal 2 yesterday for ps3, i wanted to link the psn and steam account but couldn't cause... you know.

the thing is, i really want to play it on both ps3 and pc, and yes i know the game comes with a code to redeem the game in steam, BUT the instruction says that i should redeem the game in steam AFTER i link my psn and steam accounts, so the question is this:

does anyone know if i can link my psn and steam accounts AFTER i redeem and download the game for my steam account?
