So I turned off location services in beta 3 just so I can have longer battery life. Then when using an app that sometimes uses location I got the message telling me to go to settings to change it or cancel. But, for some reason you can't dismiss this at all no matter what you press or even lock the screen. Just a heads up for everyone else that disables location services like me. Holding down lock and home to reset was the only way to remove this. Cheers!
