I doubt the answer is yes, but it's worth a try.
My 18 mo old son loves to press the Home button. That means whenever I give him an app to play with, he exits out of the app by pressing the Home button. Now he's free to flick the screens and sometimes I've caught him at the "delete this app?" phase.
So is there a way to disable the Home button and/or disable the wiggle&delete functionality (maybe in iOS 4 due out this summer)? There should be Childproof settings next to Accessibility settings!
