Just got the new iPod Touch white/silver. The only iOS device I've used previously is a 1st gen iPad running iOS 5. I'm trying to figure out how to use gestures like I use on my iPad. Like four fingers sliding up to reveal the current apps bar, four down to make it disappear, and four fingers to the left and right to switch apps. Also 5 fingers all coming to a point on the screen to leave app and go to home screen. Is there a way to enable this for my touch or do they not allow it because the screen is smaller?
