Buying content on psn with CFW
My PS3 is currently on Rogero 4.21 and have access to PSN using YAB, I was able to download a demo from PSN Store, install and play it without problems. My question is can I buy content, i.e. a game, from the store and play it even if psn is blocked again or if I upgrade to the 4.30 CFW?
Thanks in advance
