Talking about the actual Beta registration code that it comes with, not the PS3 download code? I believe you can.
The new client coming out for Phase 4 isn't out yet from what I understand.
check reading skills I actually said specifically it wasn't that code.
No need to be a ********* The code won't work anymore, but he's right, you get two codes for PS3, the code to redeem on the PSN, and the code to authorize your SE account to access the beta.
