Same here. Rumor has it that the store will be back up tomorrow and us PS3 owners can't afford to wait another month all because of some no-life hackers.
I didn't know where to put this so I put it here. The time has finally arrived for PS3. As of midnight central time, the store is officially live. Just redeemed my Jade code I've had for over a month and it works!! Check the store and start redeeming your codes!!! We're officially back!!
I had a few error codes as well. I turned my system off and on again, and it worked. I also got a few error codes trying to punch in my Klassics, but just kept trying and eventually they worked.
