I wonder if Sony will ever release more details on how it happened. One rumor out there is that a cracked firmware was circulating that somehow modified dev kit code to grant retail PS3s free access to the store. I didn't really buy that as the only reason, since it should have been trivial to just shut down the store instead of the entire network.

Really bad timing too, considering the PS3 release of Portal 2. Been wanting to play co-op with a friend Mac<->PS3.
