it sounds like people who completed the 4.45 update are having screen trouble and the people who are stil on 4.41 can access there XBM menu and use their ps3 they just cant sign in because sony must be trying to fix the problem
I'm on 4.45 and my Ps3 didn't brick, it was working fine. I still can't log in.
I didn't update and am still not able to connect, I personally think its just maintenance issues....I would bet everything will be fine by this afternoon. But again that is just my position....hopefully if it will be a longer "event" sony will tell us so.
found this on another site. Maintenance?
Its the 19th
