Issues with T-mobile to at&t mms on iPhone 4?

[hucworld]

I have three friends all of whom have T-mobile and have tried sending me pics tonight and nothing has come thru. Anyone else have this issue?

I would call AT&T. Did you activate over iTunes? Sometimes things don't get activated correctly and mms seems to be the first thing that gets messed up....
