can't remove persistent android widget (accuweather.com)
I think it is a recent Accuweather update that displays the weather when you go back on your home menu. It's really annoying as when you click on the "home" button, it brings you back to that page and not the actual menu, which means you can't navigate between applications without clicking the back button all the way.

I think I may have fixed it the brute force way, however. I don't care about the Accuweather app, so I just went in the Setting->Applications->All menu and deactivated Accuweather altogether. You get a warning message telling you that deactivating built-in apps may interfere with other applications, but I hardly think that Accuweather is necessary for your phone to work.
