I'm pretty ignorant about whatsapp, but I paged through their blog a couple hours ago, before reading this post (https://blog.whatsapp.com/).
And the fact that they had blog posts about Windows Mobile, Nokia, and Blackberry clients really stood out.
I think Google, Facebook et al probably prioritize those platforms last, if at all. So kudos to Whatsapp for their contrarian thinking.
Their blog also shows the achievements of 1M and 2M simultaneous connections on a box, which I remember seeing here before on HN. So these guys are also very talented and experienced engineers.
