I realize first of all that is somewhat speculative so please don't flame! If and when iPad/iPhone support 4G technology, does anyone know what effect that will have on those of us with unlimited data plans for 3G? My suspicion is that ATT will use the opportunity to eliminate as many unlimited data plans as possible, given their already extant throttling of data for those on this plan. Seems like this will be an issue facing us with iPad 3 and and iPhone 5.
