Hello, A guy at my school wants to sell me a Pretty new MC371CH/A Macbook Pro.. 15.3" and all the good stuff. He's a Chinese student and bought the laptop in China. It is not* one of those bootlegs that are running windows.. everything about it is right. I was just trying to figure out what the difference between the CH and the LL in the scu means. Does the CH just mean that it was a Chinese version? Can I still register it and itunes on it? Just wondering what to do. Thanks!
