I've just release version 0.1 of a new Blackberry application: Weather Watcher. It allows you to check weather conditions, and a 5 day forecast, for locations all over the world.
As I mentioned, this is only version 0.1. Any suggestions for future improvements are more than welcome!
Sorry that everyone seems to be having problems! I've updated the app to include better error reporting. Don and akosnitzky, if you try it out again can you let me know what error message you get?
@Supersonix: I'm glad it works for you. Some people have reported problems, although I'm not sure what devices there are problems on. Saved searched is something I'm going to add in the next release.
