People relax. Remember that Whatsapp is not a documented protocol. Every single feature even if it's a totally stupid feature has to be reversed and analyzed to see how it is implemented in other platforms. It's not like I can read a book "oh ok I just have to send these bytes and that's it!". I have absolutely NO IDEA how to change the status. And when I tried to reverse it, it was sent via SSL to the Whatsapp servers, so it's encrypted. Since that's a not really useful feature, I will delay that as much as possible, since what Yappari need is full 100% Whatsapp standard functionality (that is multimedia messages and contact synchronization). After that, we can think about things that are not really that useful, but they are nice to have.
