When I send an MMS message with my 7650, I receive the following content-type headers (in hex format):
84 = Content-Type
1F = ?
21 = Length (0x21 bytes)
B3 = application/vnd.wap.multipart.related
313633373636373134303E00 = <1637667140>
896170706C69636174696F6E2F736D696C00 = application/smil
When I use a T68i, the second byte (1F) is never there. The second byte is always the Length. What does this second byte mean, and how do I know that its there so I can properly decode the MMS message? I couldn't find anything in the docs of the WAPForum.
