I joined here just so I could edit this. The last guy who answered obviously had no idea what he was talking about. Xbox Live is possible over dialup. Of course dialup is far from the best internet connection for gaming, but it works. All you need is a PC with both a dialup connection and a high speed network card, and a network cable. Run the network cable from your 360 to your pc, connect to the net via dialup, right click on the dialup connection icon on the bottom right corner of your screen, click "Properties", click "Advanced', and then click "Allow other network users to connect through this computers internet connection.", select the appropriate connection, and click OK. Of course, it's dialup. ANd while Xbox Live gameplay is possible, it's very unstable and laggy. But it is possible
The original Xbox with live isn't support anymore, so no.
You go to the website and look at the bottom of the page for the number.
Heskey.
