Why is whatsapp not in the app store for iPhone?
I recently deleted whatsapp accidentally on my iPhone, and when I went to reinstall it, it wasn't available in the AppStore. I even went to the updates section and tried to locate it in purchased apps, and it wasn't there either ?! Not sure what to do. Please help. Also, when I search what's app in google and try to click then direct link that the company lists to download it in the app store, it states that it isn't available.
iPhone 4, iOS 5.0.1
