@TheNick: Always read the first post before posting, Whatsapp blocked registrations to unofficial clients.

You shouldn't have used the same SIM with another Whatsapp software, now you can't register anymore (it's kinda your fault too). You de-registered Yappari when you logged in using Whatsapp in Android, now you won't be able to use Yappari ever again.

@ everybody else:

I don't know when (and IF) I can fix it. I have tried, but as you can imagine now registration is way more secure than before. Whatsapp doesn't want unofficial clients to be around (remember they charge $0.99 to iPhones and $1.99 to Androids after a year). It needs to be hacked. I don't even know if we can do it (and if we can't it would mean the end of this project).
