I think you may be getting the new Genie News and Weather widget mixed up with your USA today app. The new Genie News and Weather came as an update with the 2.1 over the air update. That would also explain why you cannot seem to find where to uninstall the app. You can only uninstall apps that are in your data partition. Those apps show up in your Settings > Applications > Manage Applications list. Apps such as YouTube, Browser, Contacts, Phone, Genie News and Weather, etc. are located in your system partition and cannot be easily uninstalled without further rooting your device and gaining superuser access
