Hi guys, everyone

I am so very sorry to inform all of you that Yappari won't be back.

I've been very lucky to meet several people who have helped me, letting me borrow their numbers to continue developing, even if that meant getting banned by Whatsapp. I'd like to specifically thank Sicelo, KotCzarny, bmxerv and others.

The situation right now is that I can't continue development at all. Last number I got from bmxerv has lasted only two days without being banned.

I don't know the reason for these bans, nor how do they detect that I'm not using the official client. Even if I knew this, I still haven't been able to implement Signal (previously called axolotl) protocol, which is behind the encryption system.

Alternative implementations, such as https://github.com/tgalal/yowsup/ are suffering from the same kind of issues lately, with still no answer.

So... this is it. I simply don't have the knowledge that is required to make this thing work, and to be honest, I even doubt that right now anyone has it at all.

As of today, I simply think that it's unreasonable to keep asking friends for their numbers just to get them banned in a matter of hours for no real benefit at all, as testing is impossible with so little time.

I also don't think it's reasonable to keep you guys from looking for an alternative just because you trust that Yappari is gonna work again soon. Sadly, that's not going to happen.

Maybe, some time in the future, someone discovers what must be done in order to avoid these bans. If that happens, I assure you I'd be back to implement that into Yappari and try again to make it work with new encryption system, but that doesn't seem like something that is gonna happen soon.

To be honest, In my opinion, that's simply not gonna happen either. As soon as 2016 ends, Whatsapp will stop supporting S40 phones, from which most of us are able to reverse engineer the protocol. After that, Whatsapp will be able to completely change its protocol without us being able to take the slightest peak at it. And I'm sure sure they will.

So... that's it. I don't know what else to say nor how to lessen this loss for all of you. Just wanted to say that, like Sicelo said above, the N900 has always been much more than simply a Whatsapp device. It's still a great hacker's device, a great phone (yeah, simply it's sound quality is thousands of times ahead of any other smartphone I've used) and a great small full fledged computer. Even if I get myself a whatsapp compatible device, I won't stop using the N900 until it dies and I won't be leaving this great community until it fades away with last N900 that keeps working years from now.
