Emergency Mode?

I turned the iPhone off. Put it on the table, face down.


Next morning, I turn it on, screen shows picture of USB cable %26amp; an arrow, indicating that the phone should be plugged into iTunes, %26amp; an oblong window read something on the lines of %26quot;slide to make an emergency call%26quot;.


I plugged phone into iTunes, %26amp; screen indicated that the phone has been activated...


This has happened two times in a row so far.


What gives?





Thanks!
