So i got myself a ps3 for jesus day. 80 GB! (Fuckin kickass graphics) I also got call of duty 4, game of the year edition. i was stuck in a house with no internet routers nearby though, and i couldnt get it online. i ran through the 1p missions within 2 days. I finally get home, and i cant get it online. Turns out i need an ethernet cable. is this the only way, or is their some other way it goes online, without me having to buy this wire?

and 1 more thing... When i get it online, i'm gonna get all ur CoD usernames, and kick all ur asses online. i probably suck at it online, but who knows, we will see...
