I love the weather site at Accuweather.com I have recently found an even better way to have the content loaded into my bb without doing anything.
There is an application out there called Infuzer (
www.infuzer.com) there you can download to your desktop an application that automatically syncs the running 5 day forecast from AccuWeather.com. In addition you can load in travel plans and sports schedules all for free!
The only catch you need to sync your BB often otherwise the contents wont be on your handheld as it only syncs it to your Outlook, or Lotus notes.
