I admit I’m a tightwad. I like free and cheap stuff and would rather not update my PSP firmware to the latest version and still keep my 5.03 firmware. Keeping an older firmware has its drawback, which is that you cannot log in to PSN and download demos, themes, and games purchased from the PSN store. And with that, today someone brilliant and great has created us an addon that will allow us to log into PSN with older and custom firmware. No matter what CFW you are on 5.55 Gen-D, 5.0.3 Gen-C / D/B whatever, now you can access PSN using this plugin called PSNLover.
