Access Point Network change needed for messaging?

[spanky32354]

I have a Jailbroke iphone 4s that I am using on Straighttalk. Everything works great except I couldn't send MMS (pics, and messages to multiple people). I was told that a jailbreak was needed so I paid my money and did it, but still can't send MMS. So now I've been told by Straighttalk that I need to change my Access Point Network settings but I can't find them anywhere. Can someone please help????? I tried the search function but looks like I'm the only person in the world that needs to do this, lol.
