There's really only two things I can help you with that will make it easier for all of us.

Whenever there's a firmware update. DON'T ASK ON FORUMS!
Bookmark this site. It will tell you all you want to know.

Every Thursday(well almost) there's probably going to be a Playstation Store update.
Then there's you, yes you, you irritating waste of space, who want to know what's in the update...
TURN ON YOUR PS3 AND GO LOOK FOR YOURSELF! It ain't that freaking hard!
"But I'm not at home"... So what are you gonna do when you get home. Play COD4 right? ... "Yes, of course"
Well then you're gonna turn on your PS3 anyway, SO THEN YOU CAN LOOK AT THE STORE YOURSELF!

How come on every goddamn forum there's some people who are just either too lazy or too dumb to do find out about this stuff the easy way?
