This app is an advanced MMS message editor for Symbian OS & S60 devices and it resembles the classic e-mail clients. You can use this app to send files as attachments in MMS messages, regardless of their type. You can send a message with no size limit (as long as the device and network supports it), set the MIME type of each attachment, set the message subject and automatically create the SMIL presentation file of the message. Finally, you can select the recipient(s) from the device's phone book.

This app is free (FOSS), its UI is available in English and Greek and it requires the S60 FE or SE platform. (As a note, the Nokia 7650 device features a very old version of the S60 platform and is thus not supported). The app is also available in myphone.gr's MyFiles section.
