If you're an Android user, you probably know that after the latest update, AccuWeather app stopped working and everybody complains about this (any device, any Android version). It simply force closes after the launch. It seems that AccuWeather is never going to update that app, so I found a way of getting AccuWeather data on your device, under the same interface.
There are more AccuWeather apps in the Market, if you search for them. However, I've found one which really works, so if you search for "ACCU WEATHER Quick" (yes, ACCU WEATHER with capital letters), you'll get an AccuWeather app which really works. It seems to be released by Accuweather.com (nobody knows exactly), and it has a few bugs, but at least it works. Some users reported problems with the widget, problems that I don't confirm. There were also reported some problems with the accuracy of displayed information, but as I've just downloaded it, I think that the information is quite accurate.
So, go to the Market and download "ACCU WEATHER Quick" app to see if that one works for you.
