Today Sony closed the hole that gave CFW Users access to PSN (Just Sign in, No Games or Store). The RC Servers that many people were signing in were for developmental purposes and if you signed I'd be careful since we don't know much on what Sony is currently doing right now. I had posted a tutorial a few days ago and it can be found Here. Like I had said if you abuse it you will lose it. This method was only a temporary solution and for that I did not use it.
