iPhone MMS with Pure Talk

I can't get MMS working on my 3gs with Pure Talk. It's an ex-ATT phone that has been factory-unlocked but I don't get the Cellular Network screen, so I created a Configuration Profile. Can anyone tell me what the mms_override file is supposed to contain for Pure Talk? Or is there a better/easier way to set up MMS?

Thanks.

I believe MMS is not supported for iPhone for PureTalk and other MVNO's. I'm not sure of the reason why, but there seems to be be no way to set the MMS configuration. Probably Apple's fault.

1. Select Settings
