I guess I left vital information out, my iPad is also stuck in the 'lock' Where it says slide to unlock, it won't let me unlock it. All it's allowing me to do is click the OK of the popup, but the popup doesn't disappear and stays the focus. That is the same thing that occurs when I attempt to power down. the slide to power off shows up, but it's in the background and the focus stays on the popup, but again the popup appears to allow me to click the OK, but never goes away.
