Yeah I've read about this too. I agree with bro DonaldDuck taht if theres a place to get it done, its 188 or at the corner of Fa Yuen Street in Mong Kok.
I would advise against it though, cos once Sony release a firmware update, which would be pretty soon if not already, cracked PS3s may be "bricked" and as bro Harolda says, you'll have to get a new one.
I used to only buy pirate games but now only buy the real stuff, cos if the game companies arent making money, then we won't get new and better games, plus I get a lot of shit from my friends who are games designers in UK!
