I know that the 350$ bundle comes with a 30day Xbox live. Do you have to sign up for the live right when you purchase it or whenever you want. Im saying this because i want a 360 but i will need a wifi attachment. Right now I have 400$ and the only way for me to get connected is using the wifi attachment which is another 100$. Im thinking of buying COD4 and the 360 with some help from my parents, then working some more and eventually buying the wifi thing later and use my 30 day trial after i save some money.
