* Whatsapp is a free implementation of the WhatsApp protocol for libpurple.
* The implementation is not 100% complete. Currently supported features include
* message send and receive and profile pictures. In order to be able to login
* you need your WhatsApp password, which is not easy to know. As of Jun. 2012
* the password was either the IMEI or the MAC addres, but latest versions
