Yeah, store is down, but online gameplay (what I am most concerned about) has been up and running.
You said it should be fine. That meaning, as of right now, it's safe to play my backup ISOs online on PSN (while running 6.20 PRO-5), right?
I just got a PSP-3000 and permanently installed CFW 6.20 Pro-5 on it. Much props to prowler_, Rydian, and GBATemp for the great tutorials on the site.
Just one thing that wasn't clear to me: Is it OK for me to sign up for and access PSN with this CFW?
