There seems to be a good deal of 'misinformation' about just what game software you can run on an american PS3. I've just finished reading one such post, why doesn't SCEA 'set the record straight', once and for all on this matter?
The all PS3s can run games from other regions, because most games are coded to be region free. There is one recent exception, I believe it is a Atlus Persona game. The publisher does have the option to restrict their games to one region, but most do not. So if I were you, I would check on this for any new import games you wish to buy...
To those who've posted so far. Thank you for responding. I can breathe a lot easier when I place an order for Japanese PS3 software with 'Toys 'N' Joys' in HI. (A totally cool store by the way! (Very shameless plug here! wink, wink.))
P. S. Please excuse any bad grammar, or (im)proper punctuation.
