A couple months ago I had someone hack my PS3 and install CFW for me, and I've been enjoying it and having minimal problems accessing homebrew and backups and such. Although the problem is, I have no idea on the specifics of what was exactly done to my ps3, other than the general downgrading and installation of the cfw. What I mainly want to know is whether or not my PS3 can access PSN, but it's hard for me to understand guides and such since idk anything about my cfw or how it works or how I can update it. The OFW is 4.66, and the multiman client says that I'm on COBRA 7.02 firmware mode atm. It'd be great if someone could explain how to update CFWs or which CFWs are best for what stuff, and on methods for connecting to PSN. Thanks.
