It's probably worth holding off updating your PlayStation 3 firmware to version 4.45, as reports are flooding in that it is causing issues with consoles.

Many PlayStation 3 owners have taken to the official US PlayStation forums to report that the update has bricked their consoles, causing it to freeze on the ribbon screen.

It's unclear whether the update is causing the above problem on all consoles, but it's probably worth holding off until we get the all-clear from Sony.
