I feel like an idiot here BUT, I let my Grandson use my IPad 1 yesterday and the Apple App store icon is gone from the device home screen! What I don't know is was it gone before he used it and after I upgraded to 4.3. This is the first time I have looked for the store app since upgrading. First off, I am the only one in the world who has lost his app store icon, right? I did't think it could be removed from the device (like other Apple device apps). I know how this sounds, but it's happend to this device and, no it's not hidden in another screen, etc. and it is still visible in the settings section where it shows my Apple ID. Any ideas??
