The NMIT 4.0 is able to create multipart/mixed content. The Nokia 6220 advertises in its Accept HTTP header that it supports multipart/mixed content. However, I am unable to create an example that works with my 6220.

Does anybody have a working multipart/mixed example available on the web for the Nokia 6220?

Does anybody know which additional documentation I can read about the support of this format for the Nokia 6220?

Thank you and best regards,
