iPad frozen by "find my iPhone alert" box
My iPad is showing a "find my iPhone alert" box (xxxx iPod touch has been found) that won't dismiss when "ok" touched. Background "slide to power off" or "slide to unlock" don't respond, so I can't restart the iPad. What do I do next?
iPad (3rd gen) Wi-Fi + Cellular, iOS 6.0.1, AT&T
