How to get data and mms on iPhone 4S with net 10?

I have an AT&T iPhone 4S that I just put on with Net 10. I don't have mms or data, I was informed that if I configure the APN settings to their settings, I would get mms and data to work. But, it also says that iPhone users may have to do more research/configuring in order for everything to work. I just want to do it the correct way without unlocking it or anything.

You would need to jailbreak it.
also you will only get 2g data
