After a week of trying to get mms to work on my imagio i managed to stumble upon a few registry settings on the phone to make it work using the manila 2.5 sense. Now I've tried the mms fix cab and all that's done for me is cause problems on my phone, as well as not fix my mms issue. So after a week of experimenting on my phone with the two main folders in the registry: arcsoft, and jataayu i was able to fix the mms setting as well as document everything i did to make it work; i even reset the phone again and installed sense as well as the cab i'm going to put up and it worked! Once you've done install the mike304 mms fix cab and Then change the reg settings \\hklm\software\jataayu\mms\profile\verizon and change the mmscurl value and put your phone number where it says your phone number example below:

Credits go out to the person who said to put this ?X-VZW-MDN and honestly i don't who it is, also to jmart518 for being so kind to make the cab for me. You'll need a program like resco explorer to edit mmscurl entry. I can't guarantee this will work with any other device except the imagio. Thank you.
