If the rumors are true, (taller iPhone this fall, 4" screen, 1136 x 640 resolution) how will this affect the way text is displayed in Safari? One of my biggest issues with the current 3.5" screen is that I find text to be too small too often. I realize that in landscape mode the iPhone will benefit greatly from that extra half inch. But what about in portrait mode? Will text appear larger? Or will we simply be getting a bit more screen real estate?
