I have a itouch and it ended up getting locked. I ave tried to connect to iTunes and it does not recognize it. Tried the 2 help options and they did not work either (turn off and hold power button, connect to itunes).
No sure if it makes a difference but i have a iphone 4s, iphone 3 and a itouch. I do not use itunes much so I am out in the dark. Also Apple says to bring it in for service.
