Sony has rolled out their latest firmware update, supposedly
adding trophy notification options and improving overall system stability. However sadly this doesn't seem to be the case as many users on the PlayStation Community forums
are reporting issues after updating their PlayStation 3, with some consoles going completely unresponsive.
Sony has yet to address the firmware issues caused by the latest firmware update but for now we strongly recommend not updating your PlayStation 3 in hopes that the issue is fixed shortly.
Update: Sony has responded by pulling the update while they investigate further into the issues from the new firmware. We'll have more as it comes to hand.
