hey dude, i tried the following and it worked. 1) Re-install Wazapp on the N9 2) Download WhatsApp on another device which is connected to wifi with the sim card removed 3) Start WhatsApp on that device and register with the number of the sim card in your N9 4) You should receive a text with the registration code on your N9 5) As soon as you see the text on your N9 turn off the first device (the one you resgistered on) 6) Start wazapp on your N9 and manually enter the 3 digit code you received in the text.
