Here are the Rogers MMS settings. Confirmed and working.

Follow the directions for creating a new APN using fAPN.

Connection Name: Rogers MMS
Connection Type : GPRS

Access Point Name: media.com
Username: media
Password: mda01

Advanced
Enable "Use Proxy"
HTTP Proxy: 172.25.0.107
Port number: 8080

Finish. Done.

Use fMMS to send. It will resize and you'll see a MMSC response of "200 OK". Good job, you're a winner.

For incoming messages, you will get an "MMS push" notification, connect to Rogers MMS, open fMMS and you'll see the message.

Big up to frals.
