I guess I don't really understand 4G speed on a cell phone. I can stream all my music from Pandora without interruption on 3G, and even stream high quality movies from Netflix without interruption on 3G. So in my mind, 4G is useful for mobile wi-fi hotspots, or for massive file downloads. Can someone explain to me why 4G is such a big deal for cell phones? Full webpages load just fine on AtomicWeb on my iPhone, I can't imagine that I would need that much more speed.
