So you want to use the phone's internet connection to play a game, correct? Are you talking about our game TSR or the original Tiberian Sun? I would imagine that the original TS game would probably be playable over dial-up (though this isn't really dial-up here), but you would probably have a great deal of lag trying to play any FPS game over that type of connection. The reason is that while you might be able to get good bandwidth, the latency would be fairly high. (bandwidth is the size of your pipe, latency is how long it takes stuff to travel through it)
