I did the firmware update early Sunday morning. Got through the password change alright, despite not using the PS3 I created the account on (that'd be my friend's YLOD'd 60GB model). Wasn't able to log in to PSN with the new password right away (this has happened to me before). Was able to log in to PlayStation.com with the new password. Got a confirmation e-mail, which Gmail doomed to my spam folder. Eventually logged in for a few minutes to update the trophies I didn't gain during the past month, and see the PS Store was down. Ran into a "server under maintenance" error later in the evening. And got back on again a few hours ago.
