Okay, I got the LG fathom about 3 weeks ago and i popped my att sim in and it calls and texts and everything just fine but i cant send or receive mms. I have tried configuring the connection settings and I have tried a couple different cab files but neither work. I need someone to help explain EXACTLY step by step how to set up mms on the lg fathom, please. I've followed general mms settings guides but I still can't get it to work so if someone could help me it would be sooo much appreciated. Even if you just give me a link to a step by step guide for the fathom that would be fine. Well thank you
