Weather.mobi is the first of the premium dotmobi domains to go live.
The registry made an official announcement a few hours ago and the site is already up and running.
Unlike paramount.mobi, that reserves a lot of its premium content for US subscribers only, weather.mobi provides local weather information for even the smallest of Irish towns.
The Weather Channel have been providing their forecast data in a wide variety of formats for quite some time, so I guess it should come as little surprise that the mobile site is such a masterpiece.
