Google Sky 1.5.1 worked fine on my Driod with 2.1 but now it is frozen showing at the south pole centered in the display. Powered down relaunched and removed the battery more than 3 times with no change. BTW an app called GPS Anywhere that displays a compass rose continues to work fine, that is it acurately points to north no matter how much I move the phone. Where as Google Sky just shows the south pole and doesn't move.
Perhaps there is a setting I'm not seeing that got changed on Sky?
