I have a little trouble about MMS, too.
First of all, I have many problem before with cooked VZW ROM, so I decide I will try dcd 1.6.7 clean ROM. This ROM is great! (btw, thanks dcd!)
I can send the MMS messages because I manually set my config like:
Server name: Verizon Wireless
Connect via: #777 Connection
Sending limit: 248k
WAP: WAP 2.0
But, because MMS package is built for Sprint,, it say me error: 1012 cannot provision Sprint vision data services when I tried to receive MMS message.
This is minor issue, so I'm no worry about it.
I think because someone mention MMS issue today, maybe I will mention mine too and see if anyone know the reason or "easy fix". Maybe its just I need OEM VZW MMS App, but I search it and no find it. So, please forgive me for bothering you all again... Thank you all for your help though.
