Proper 700W/WX MMS settings for metroPCS
 

I have tried editing nvm files as written in Ultimate Treo Flashing Guide but It doesn't work. I've tried to install VZW Arcsoft but it won't install. I out googled google to no avail. I searched this forum only to find cricket settings which I've tried(I replaced mycricket.com with mymetropcs.com). This is me asking for help only after I have searched endlessly for Treo 700W/WX MMS on metroPCS.
Please help me.

Thank You,
Mannie
