I'm having issues with getting fMMS 1.3.3 to work.
I did have it (i think a previous version) working with the same settings (i think) before reflashing my phone.

I set up the application with my providers settings (Telenor, sweden) as follows:
Name: services.telenor.se
MMSC: http://mms/
Username / Password: <empty>
HTTP-proxy: 172.30.253.241
Port: 8799
IP-address: 172.30.253.241
Mode: Havoc

When i try to connect manually to the MMS-connection it works just fine, as do it when fMMS automaticly connect.

When i try to open an received MMS, this is what happens:
"Downloading MMS"
"Operation Failed"

Here is the complete log (deleted old log with fMMS closed, then started fMMS, clicked on a MMS then closed fMMS after "Operation failed")
