Hi all, I'm hoping to get some guidance from those wiser than I. I'm having a problem with an iPod touch, it won't respond to finger slide at all but will to a double tap on the screen, I can get into the settings by double tapping on the icon but it won't slide down for me, have tried resetting by holding home button and the sleep button until the apple symbol appears but still no joy. I would be grateful for advice. Thanks
