My settings that seem to work for Vodafone Australia

Used fAPN to create a second connection

Connection Type: Packet Data
Access Point Name: live.vodafone.com
Username: EMPTY
Password: EMPTY
Proxies:
Use Proxy: tick
HTTP proxy: 10.202.2.60
Port number: 8080

In fMMS I set it to use the access point I defined above
MMSC: http://pxt.vodafone.net.au/pxtsend
Your Phone Number :+614.....

These seem to work for me, but I have not extensively tested them.
