no MMS on AT&T running T-Mobile 5.1

[timbecile]

So I unlocked my wizard which is at&t and put on T-Mobile 5.1 software, and now I can't get any MMS messages. I figure that there's a settings problem, but I don't know what the settings should be. anyone have any ideas?

search for Network Wizard tool on these forums..
or just download this package from http://forum.xda-developers.com/showpost.php?p=2194969&postcount=3
it has the tool in there... worked like a charm for me!
