New here so I'm not sure if this was discussed before, but I'm at work and was thinking.... With AT&T all worried about data usage is it possible for the iPhone to get the internet though the computer instead of using 3g? I know we can't do this now, but could it be something we see in the future? When I am at work I leave my iphone plugged in all day and stream internet radio (headphones don't reach my computer and it's easy to use), and surf right from my phone. If this was possible it would cut my data usage in half. Thoughts?
