I rang Sony (Australia, as the New Zealand helpdesk closes at 5pm), and they said they can't lift the 24 temp suspension.
I took time off work too. Ah crap! I might go to blockbuster and rent a game so I've got something to play tonight/tomorrow. If someone would like to suggest a game to play to get me in wipeout mood, that would be cool (I was thinking Pure [the motorcross game], but I don't want to get sick of racing).
