DO NOT UPDATE YOUR PS3 FIRMWARE
Sony released a firmware update last night (4.45) that is rendering some systems useless. They’ve pulled it down for now but I would suggest that you hold off on updating for fear of bricking your machine.
Sony announced that they are aware of the problem and are working on a solution. With gamers being so fickle I wonder if this has scared some of their new supporters off after such a great week of PR for company.
We’ll keep you posted with updates as we get them.
