Ok, here's a quick fix: SDK doesn't let me build deb file, but you can replace binary file (it's in /opt/maemo/usr/bin folder) if you don't want to wait for ceene's official release. Whatsup new protocol is different to yappari, so I've taken changes from coderus sources (say thanks to him) to make it faster (otherwise I need to make a lot of changes). New protocol funcions doesn't work yet (you will notice it in group chats), but at least you have yappari working. @ceene: write me to cepiperez@gmail.com and I'll help you with all new functions. I've attacched the modified source files too. EDIT: binary exceeds attachments size, so here's the link: https://www.dropbox.com/s/5y6k06ynuigzp19/Yappari?dl=0 EDIT 2: Say thanks to HtheB too cause he was the tester. EDIT 3: F_ck whatsapp! We will hack you forever! Enjoy!
