can't install whatsapp
A friend of mine shared his Apple account with several other people. They all installed whatsapp. Then he switched to iphone 5s (was on iphone 4s) and now when he goes into the store, there's no option to install whatsapp, just 'open'. But when he tries to choose this, nothing happens. He asked his friends to remove the app and still he can't install it.
