Missing MMS Option

[Late85js]

I have been going crazy searching for the reason why I can't go beyond step 3. I have internet and i can receive text message but can't send or receive picture messages. I have install Arcsoft tried to edit Arcsoft with task manager but i guess I'm not that smart. I'm would like anyone to direct me on how to to do this step by step or a link that can instruct me on how to. Trust I've search and search all over.

3: Click on "Menu" and select "MMS Options" then select the "CDMA Servers" tab.

4: Add a new server with the following settings:

Server Name: metropcs
Gateway: wap.metropcs.net
Port number: 3128
Server address: http://mms.metropcs.net:3128/mmsc
Connect via: SELECT THE CONNECTION YOU SETUP ABOVE
Send limit: 500K

I can't go pass this step because MMS Option is not available. I have install Mighty Rom 4 because I have window mobile 6.1

Please help, I'm so helpless
