Ok, I'm asking this here, because you wonderful MacRumors people have yet to fail me. 
I REEEAAALLY hope you guys can help, because I don't want to call Net10 customer service again, as none of them can understand English, it seems. So, I bought my friend's old AT&T iPhone 4 off of her because she upgraded to the 5s. I bought the SIM card and unlimited everything plan from Net10, and it came in the mail, and I activated it, etc., etc. At first, I had calling and SMS, but no data. I called Net10, and they walked me through some things, and I had data. So, now I can call, send and receive SMS, and use data. However, I am unable to send or receive MMS messages. I did a Google search, and found nothing helpful, as it was all solutions for iOS 6, and there aren't the same cellular options on iOS 7, which I have on my iPhone. I tried to revert back to iOS 6, but it doesn't allow you to do that now. I am really frustrated by this. Can anyone help me? Apparently, iOS 7 doesn't allow you to edit your APN settings now, so I can't try the settings suggested all over the internet. I'd really love to be able to send and receive MMS. Any help at all would be GREATLY appreciated!
