Ok guys, here is hoping one of you can help me out on this one as I am rather confused. Must be my age (66)!
I own 2 N9's, each with a sim with the same phone number. N9 number one is registered with Wazapp with no problems. I do know that registering N9 number 2 will mess up the first registration.
Is the following solution possible without jeopardising the first registration.
1) Switch of N9 1
2) Download Wazapp on N9 2
3) Ask my friend with HTC Android phone to register my phone number.
4) When registration code is sent enter this in N9 2.

Is this feasable or are there any other safe solutions?

I specifically ask thedead (or living) 1440 as he is extremely knowledgable (nudge,nudge,wink,wink) on this subject.

Muchos gracias in advance!
