How I can activate MMS on an iPhone 2G with firmware 3.1.3? PLZ HELP!?

I have the first generation jailbroken and unlocked and I use it TMobile. I'm currently downloading 3.1.3 ActivateMMS 2G but does nothing. Should I change my MMS settings or something else? Or someone knows another application that works?
