If the button works for some things and not other things, like you said, it's probably software related.
If the restart didn't fix it, then the next step is reset. Go to Settings, general, reset, reset.
If that doesn't fix it then try the restore from itunes.
If it still doesn't work, then it's time for a trip to the apple store for testing and corrective action.
