download whatsapp blackberry 9900

Hey, Sorry but I'd like to know if there is any way to install WhatsApp and really use it on my Bold 9900, it has a software Update from OS 7. blackberry id login bermasalah 1 but I don't know the exact name I tried to download it from beta whatsapp com/ota but there is always a screen that says that I need to update the application because the app is too old to function
