Lots of correct caps in the title! In all seriousness....... so here is where I am at. I am on an ATT MVNO. iPhone 4 32GB. Unlocked by ATT. MMS will not work. I have tried a non MVNO sim and it allows me to edit the APN settings however when I put my sim back in it does not, I assume this is b/c it is an ATT MVNO. Any of the sites I can find only provide profiles for the APN and not the MMS portion as well. Any way around this without jailbreaking? I am not new to this and have done some looking and see nothing thus far. Thanks in advance for any help.
