When you download an app from the Appstore you are usually prompted for your password or sometimes you have to click ok to a rating for age 17 etc. The bug I ran into is if you are prompted for something and you click home it pretty much makes the enter OS unresponsive (I'm assuming because the prompt box has focus but you can't see it to type in it). - You cant "slide" to power down the phone either to restart it. - I ended up holding the power button + home until the screen eventually went black and just pressed power again to boot up. This is just an FYI for you guys.
