WhatsApp had originally said that they weren’t going to do an app for BlackBerry 10. Seems they didn’t think BlackBerry 10 was going to be successful and thus not worth making an app. Since we know that BlackBerry 10 has been selling really well, they have changed their minds. Now they are in the process of making the app for BlackBerry 10 and should be out soon.
The confirmation email from the WhatsApp Support Team:
“Hello, thank you for your message. We are working on a native client BlackBerry 10 and soon we will have more news to share. If you have other questions or concerns, please do not hesitate to contact us. We will be happy to help! WhatsApp support team.”
