I'm looking to buy a 320GB PS3 (this one, specifically). I have two simple questions on it, as I have no experience at all on PS3s. 1 - Is this a Slim or Fat model? 2 - Are all PS3s really region-free (for PS3 games)? Some friends told me that some PS3s are regionlocked and some are region-free, and I'd like to be sure about this. Thanks in advance.
