At&t mms on Tmobile touch pro2
 

Hi, I just got an htc touch pro 2 (was on tmobile unlocked for at&t) I am still trying to figure it all out and everything works fine except the mms. I have looked every where but cant find anything to help =/
I cant send or recieve mms at all. Has anyone else had this problem?
If you do or did how can you fix it?
