t-mobile mms settings

[Guest stretchy]

I have a C500 I am using with a t-mobile sim, I have checked the settings on this site and others, and although I can access gprs with no problem, I can't get mms to work. Has anyone here got it working and if so how? I believe the c500 is the same phone as the sda, and I have been talked through the settings by t-mobile but still it doesn't work.

Anyone?

I used to have a Motorola MPX200 and if I remember correctly, I could never get T-Mobile's MMS service to work on it. I think it has something to do with Windows Mobile.

But anyway, I'm in the same boat...so anyone know how to get T-Mobile MMS to work? (I have a SP5 by the way.)
