I use WeatherBug Direct and WeatherBug for Bold simultaneously so I can get a temperature reading and the weather conditions without pressing any buttons or scrolling.
yeah you need BBmaps because Weatherbug has a GPS feature that will give you the weather based on your GPS location, very cool. I had weathereye, trust me its worth loading up BBmaps and then installing Weatherbug, its much better. You have to change from the Att theme to any other theme, then connect to desktop manager and then load maps.
If you do not have BB Maps then it will do that if you installed the app that requies it. Do a battery pull and then delete the app.
Then you can install Weatherbug that does not need BBMaps from your phone's browser:
