What does it take to have a new carrier approved as an iPhone Support Carrier?

Boss Cellular is a relevantly new Quad-Carrier MVNO that uses Every Tower from Every Major carrier in the USA.

• Boss Cellular (CDMA) uses the "Red Network".
• Boss Cellular (GSM-A) uses the "Blue Network".
• Boss Cellular (GSM-T) uses the "Pink Network".
• Boss Cellular (PCS) uses the "Yellow Network".

On (CDMA) plans, (PCS) plans & (GSM-T) plans - When we activate an iPhone, the phone is configured OTA (over the air) by simply turning it on or in some cases, going to: Settings > General > Reset > Reset Network Settings.

With an AT&T iPhone, when we insert the SIM card that is activated on the (GSM-A) network: Talk & Text work immediately but the user has to connect to WiFi and go to: http://boss-cellular.com/BossCellular.mobileconfig to install the profile.  The profile allows the Mobile Data APN settings to be updated but...  No MMS (Picture Messaging).

The problem is: MMSC settings can no longer be updated using a profile.

With newer AT&T iPhone devices, the MMSC settings cannot be updated manually.

For MMS messaging to function on an MVNO, the MMSC URL must be updated to:

http://wholesale.mmsmvno.com/mms/wapenc (or) http://mmsc.cingular.com

I know you can unlock an AT&T iPhone as long as it's paid off, etc. but we're interested in making Boss Cellular (GSM-A) an iPhone Support Carrier so the carrier can inject the profile over the air when a GSM-A SIM card is activated and inserted into an iPhone.

It sounds like we need to have Boss Cellular (GSM-A) added as an iPhone Support Carrier?  Does anyone know who to contact to make this happen?
