Is anybody else's Rock not working? Mine will start up and then just sit there with a blank white screen. I have a couple other app store apps that are crashing to but those should get updated soon. And my Cydia has always been screwed up with loading errors everywhere but now it actually seems fine. I guess if this doesnt get worked out Ill just have to go back to using cydia so whatever, but is anybody else having the same problem with Rock?
