OK, so I bought a Pre that was flashed, and kind of accidentally updated to 1.4, which messed everything up. I figured out how to load the PRL, got WAP going and the proxy. I just can't figure out MMS. I just used a Meta-Doctored 1.4 ROM I made to bypass the activation, and took it from there.

I am hoping someone can give me a hint as to where I need to look, or what to do. I would love to be able to send videos that I make with my Pre via MMS!

Thanks
