how can i tell what region my 360 is locked to? (it seems to be running english as well as chinese games.) also i heard it's possible to install a game to the 360 HD and play it off that. i have the iso, how do i move/install it from my pc to the 360? (do i have to burn it to a disk or can i use a lan calbe or external usb hard disk?) i have a double layer burner on my laptop and a 60gig 360.
