Some people have found that flashing this first makes it work for them. I personally haven't ever had to do that. So u can flash it or try without flashing it. But this zip alone won't fix it... Do the rest

You need to get your Msl number first....
Now there are 2 ways to get that
1st. Just call boost and ask for it.. The easiest way to get it!!! And you can skip step 2
2nd. download the app alogcat from the market..
Open the app and pause it. Then hit filter and type msl. Then unpause alogcat. Now hit the home button open your dialer and hit ##3282#
Now click edit and enter 6 numbers of your choosing. It will say wrong code. Dont hit the back button. Hold the home button in to open recent apps. Click the alogcat one. And you should see a 6 digit number. . that is your Msl. Take a screen shot or write it down. Or both
ONCE YOU HAVE YOUR MSL MOVE ON TO THE NEXT STEP
Here is a video I uploaded to youtube of me changing the mmsc url and the mms proxy... https://www.youtube.com/watch?v=Cdld647GlHU&feature=youtube_gdata_player
3. Now open the dialer and hit ##3282# hit edit and enter your Msl number now find where to edit your mmcs URL. Change it to. mm.myboostmobile.com and swap the 7 for a 1 in the port just below it.
They should say exactly what it says in my screenshot for mmcs URL and MMS port.
Now test sending a MMS to someone.
