A friend of mine had a problem where his Motorola Droid was stuck at the message:

Loading Data Please Wait

This occurred after the 2.01 update. It looks like this problem is caused by the Weatherbug application. You can do a few things to solve this issue:

• Uninstall Weatherbug.
• Go into Weatherbug, enable your location and disable notifications.
• Use an app to close the Weatherbug app and processes.
