Take a look at Frame 6. The Nokia is not sending the certificate. This corresponds to the error_log messages showing the certificate is missing: peer did not return a certificate.
I have seen this issue when the server is missing the certificate chain that issued the client certificates. I believe the error_log is saying as much: [Hint: No CAs known to server for verification?]
The server sends the client the CAs it trusts. The client sends back messages using client certs issued by those CAs.
I know this is late, but according to this msdn article client certificates are not supported in Windows Phone 8.
