Just like how Sony isn't gonna charge this repair if it comes down to a mass recall? doesn't matter.
sony's blog and it's twitter are the best for updates, sankaku complex is the 2nd best so follow whatever, i'm just part of sankaku's twitter lol.
and yes it seems to be an internal clock error thats conflicting with the OS clock. They don't know EXACTLY what's causing it but if the internal clock itself is the main cause, than it will come down to a recall, there is no software update that can fix it.
EDIT, this also only affects games with trophies involve or downloaded games. SO SC4 still works (♥♥♥♥♥ straight) and Valkyria Chronicles for me. But FFVII isn't and MvC2 reverted back to the demo.....
but PS2 and PS1 games you own on disc work too, assuming you have a 60 GIG like myself
