I'm an AT&T customer and will likely upgrade to an iPhone when my current contract runs out in early May. "MLB At-Bat" sounds like the perfect application for us baseball fans, but can a person who already subscribes to Game Day Audio use that from the MLB site on the Internet through the iPhone instead? I don't subcribe to GDA but I do subscribe to a couple of similar streaming audio sports services online. Can I still listen to them through the iPhone without any additional applications? This would seem to be the same as listening to Slacker online through the iPhone. I've played with a couple of friends' iPhones in the last few weeks, and it seems a person can do virtually the same thing online with it as he would do on his computer at home. 
Also, what are expected to be the differences between the current iphone 3G and the brand-new one coming out in June?
