No ones really talked much about this, but if you take a look at the UK iPhone, the weather icon says 23 degrees. If you use Celsius for the Weather, it still says 73. http://www.engadget.com/photos/o2-uk-iphone-gallery/404753/ Obviously, the Calculator Icon was updated as well. But, at one point the Clock icon was showing the actually time, instead of 10:15 like it is now, but that has changed back now. BUT, for the Weather icon to update, and you aren't a wifi network, it will do it over edge. And of course, if the weather icon is updating each time you go to the home screen, you won't be able to get a phone call. Who would want to see the icon update to current weather?
