I implemented the SMS registration (and the phone automatically captures the SMS you don't need to type the code manually) and I tested using it scripts in a web server (so I don't hammer Whatsapp servers).

But now I need to find a friend that is not currently using Whatsapp to borrow his SIM and test it on the device. All my numbers are registered already.

When I test this I will upload the 0.0.4 version and anybody can register using it.

The voice method for registering will be implemented later.
