Ladies and Gentlemen, it's finally here, the one you've all been waiting for.
Wazapp is a third party whatsApp client for N9, since WhatsApp Inc. have failed to make one for the platform (even though more than 12,000 people have asked for it!).
This is v0.1.8 and it's currently in beta phase but I have installed it on my N9 and it works pretty well, it has the basic functions of whatsApp; send/receive, push notifications, status update...
here are a few screenshots I took:
BIG thanks to tarek for making a client for WhatsApp on the N9.
remember to email the developer at email@example.com if you encounter any issues.
Also and most importantly, you can donate anything to the makers of this app for their hard work and making this possible, just go to wazapp.im, you can also download the app from there!
