From the developer:
Messagingtoolkit-mms is a C# and Java library that can be used to encode and decode MMS. The encoded MMS can be sent to a MMSC through MM7 protocol, GPRS/3G modem or GPRS/3G handsets through MM1 protocol.
MMS can be sent using the built-in MMS slide feature, or you can build the MMS message yourself. You can also save the MMS file to be sent out later.
