If anyone could point me to a useful discussion, worked
example, or specification for this, I would be grateful.
Look at the WSP multipart encoding specification.
Are you just meaning the binary mms file - or the binary mms notification?
If you have a look for:
WAP-203-WSP-2504-a.pdf
WAP-209-MMSEncapsulation-20020105-a.pdf
(There may be newer versions of them, I haven't checked)
Also, a nokia document:
How to Create MMS Services_v3_21.pdf

And put aside a week to stare at the WAP specs until your eyes drop out.
They don't make this stuff trivial to understand, but its quite logical once
