Currently, i'm on the latest deb (wazapp-11092012-0000.deb)
I do all the way from scratch by deleting and uninstalling all necessary files and account.
Restart phone, re-register, re-install.

I manage to get myself to connect, but it seem to be one-time basis.
I tested by whatsapp-ing myself, and it stay as red and stuck.
I menu quit and reopen whatsapp, i then receive whatever i send to myself.
It is always the case with multi tries.

Not sure, if it is intended to be working like this? (at least for now)

Note: I'm permanently on 3G/3.5G(with the awareness of switching between wi-fi and 3G will disrupt the connection).
