Hi I just recently bought new N9 and now my older one is going to be my new "stay-at-home" phone. Because of this, I will need to install Wazapp on my new phone. What I am wondering, however, is that isn't my wazapp account tied to my IMEI or something? I am worried, that as I now register with my new phone, this will cause errors or failed logins for my old phone if I use wazapp on that as well. I would really like to keep me the option to change my sim-card from phone to phone and still have and working wazzap account all the time. But is this possible?
