I was wonder what the general opinoins where for how well the iPhone works for getting up-to-date weather? Do all the normal weather sites (weathermiester, NOAA, Weather.com, intellicast) work well on the iPhone? I know this depends on the AT&T coverage areas, but how well does the iPhone work for (hypothetical) in-flight updates? I know it is not as good as XM weather but just wondering if it actually would be acceptable.
