My sister and I each have itouches. Hers is a newer version. We both use the same account, and sync them with the same computer. The thing is, when I download an app or get a notification, my sister's itouch does the exact same thing! But it only works one way, because when she downloads an app or gets a notification, my itouch doesn't get it. It's kind of getting annoying. Is there any way to break the bond between our itouches??
