Go to Voice Search and speak "open apn"
Open the apn settings and it will most likely be blank.
Menu>NEW
*NOTE* THERE MUST BE 2 APNS FOR MMS TO WORK!
For the first, fill in only the following fields:
Name:
home
APN:
Boost_Mobile
leave everything else blank except APN Type near the bottom. Enter
default,supl
Now hit menu save.
Once again, make a new apn by hitting menu>new

Password:

MMSC:
http://mm.myboostmobile.com
MMS Proxy:
68.28.31.7
MMS Port:

MCC:

MNC:

APN Type:
mms
Not now hit menu save.
*NOTE* ONLY ONE APN WILL BE SELECTABLE.
This should be the APN named "home"
Click the little circle on the right to select (may be hard to see)
Now hit home. Then reboot. This worked for me tested and true.
Let me know if you have any issues, i can try to post some screenshots later.
EDIT: If you do this and still have issues, I should mention I replaced apns-conf.xml with the one from Blood's CTMOD. So if the APN alone doesnt work, replace your .xml file in /etc
