ATT MVNO MMS Issue on ATT Unlocked iPhone 4

[Lucky736]

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.

Well if you are jailbroken, get tether me from cydia, u can then edit the apn and all that stuff, just put the correct settings in and mms will work. If you're not jailbroken, there is a trick although I haven't try it myself, put a non att sim in, tmobile, simple mobile whatever, it will let u get into the apn setting and all that stuff, while in that screen, eject the non att sim out, put in the sim u want to use, and proceed to put in the correct settings, people said it worked but I haven't try it myself. Give it a shot

Ah. I had exited the screen hoping it would save the settings. I'll try swapping sims while still on that screen to see if the results are any different.
