MMS2R by Mike Mondragon

MMS2R is a library that decodes the parts of a MMS message to disk while stripping out advertising injected by the mobile carriers. MMS messages are multipart email and the carriers often inject branding into these messages. Use MMS2R if you want to get at the real user generated content from a MMS without having to deal with the cruft from the carriers.

If MMS2R is not aware of a particular carrier no extra processing is done to the MMS other than decoding and consolidating its media.

MMS2R can be used to process any multipart email to conveniently access the parts the mail is comprised of.

Contact the author to add additional carriers to be processed by the library. Suggestions and patches appreciated and welcomed!
