I updated to 4.0 the other day and today I got a white screen and an unresponsive google maps app. I have never had problems with maps before except for some inaccuracy. The menus worked but normally you get a loading pane, but I didn't get that. Just a gray grid then immediately to white screen. I have fixed it by uninstalling the updates and reinstalling it but I was wondering if anyone else has ever got the white screen. Do you think this is a 4.0 problem or Google Maps problem, or an isolated incident. Also it's so frustrating when the GPS can't find my location. Makes Maps useless.
