mms on vz xv6800 after updating to sprint rom

[semp10]

I am hoping someone has a solution for my problem...A friend upgraded my xv6800 with sprint rom 3.35.651.2 and radio version 3.35.04..everything on the phone works great..I have gps functioning and full youtube my only problem is my mms messaging is completely gone...Is there a way to get it working without having to reflash my phone since I dont want to lose all of the stuff thats been done on it already. If someone can give me a guide to fixing the problem it will be greatly appreciated. Hate to sound like a newbie but thats exactly what I am when it comes to all this stuff.
