I've had my first iPad2 for a few days, and it's driving me mad! When I try to order a new App, I tap on FREE and nothing happens. I click again, and again. . . and it changes to a green INSTALL. I click that, and nothing happens. I tap again, and again, and again . . . and it changes back to FREE. Having gone in circles like this for ages, eventually it may say DOWNLOADING. I'm asked to enter my password, which I do, correctly, and it says it's incorrect. Aaaaargh! Any suggestions, apart from extreme patience?
