I use my Mogul to connect to the playstation network all of the time. First get the application called PdaNet from
here. Install the application on your PC and phone. Then go to the "View Network Connections" folder on your PC and enable "Connection Sharing" on the connection called PdaNet. Once these steps are completed all you have to do is connect a network cable from your PC to your XBOX 360 and it should be able to connect. The speed is about 2.4Mbps. I've even connected my PC to the "connection source port" of a wireless router and connected wirelessly. I know, I'm crazy.
