That isn't necessarily the fault of any of the patches. Any console can freeze or crash just like a computer. That's technology for ya!
But it shouldn't freeze that often for one game. My PS3 has hardly ever frozen (maybe a total of 3 times for my 30+ titles combined, all of which I have played extensively). Meanwhile, I've had dozens of freezes for Fallout 3 and New Vegas each. I've stopped play Skyrim, but it froze 3 times before I did.
My original Phat PS3 got YLoD immediately after a Fallout 3 freeze, and my Slim model after that got it's disc reader completely putzed up after a New Vegas freeze. It's unhealthy for the system.
IF the patch works then does that mean we can use autosave now??? freezing wont be a problem if so

Except when it freezes
during an autosave and the save becomes corrupted and you lose hours of play.
