Should an unlocked phone from another vendor be able to receive MMS?



I have an unlocked Samsung phone (originally T-Mobile) that I'm using with
my Cingular SIM card.

Voice and text (SMS) work fine.

I understand that anything involving the Internet won't work because
T-Mobile's GPRS is different from Cingular's GPRS.

However... I thought MMS would work. What is actually happening is that I
sent a "picture message" from one of my phones (Cingular) to this one, with
the intent of using it as wallpaper. And although I can see that it is in
the inbox, I can't retrieve it. I get "Retrying..." ad nauseam.

Is this an expected artifact of the fact that this phone has T-Mobile's
firmware? Or should it work?
