Could someone please tell me how to (or if it's safe to) downlaod the call of duty: world at war title update that came out this week. I would like to host lobbies and such or just mess around on live with people so I would like to know how to get the title update. My xbox is a triple-nand slim (one rgh nand, one jtag nand and one retail nand for live) I want to update on my retail nand. Please help, thanks.
