Back when I got my BlackBerry Bold 9930 I was saddened that AccuWeather did not support the latest devices. Now that I am using a Curve 9350 I noticed that AccuWeather has updated their app to support the latest BlackBerry 7 crop and the app looks really good. It is having issues on some older Storm devices but my Curve is running just fine.
