Not released to the "public" there are advancements being made, but slowly. Also as the PS3's drive was never hacked it would be unlikely that a drive hack would become available.
I would presume that were awaiting some form of mod-chip to be developed, but who knows when that will be. Console is nearly 2 years old now, and it was sometime before the 360 was hacked "publically", and even longer for the PS3 to be hacked.
