[Fix] MMS for VM/Boost Running Sprint ROM - HTC EVO 3D

In no way did i write this. I stumbled onto this here http://forum.xda-developers.com/showthread.php?t=1794956 (many thanks AlpineMan btw) and have seen the question here in the Evo 3d section a few times and thought it was worth a share for those running a Sprint ROM and VM or Boost service. I did step one and it worked like a charm. And to me any fix is a good fix. Especially in the land of root phones.
Method 1 - (the real fix, but requires a rooted phone):
***UPDATE***
I've confirmed that this method works on Jellybean ( 4.2.2). Tested and working on VM Evo 3d
1a) Download this working Sprint APN xml file: https://www.box.com/s/40x5ac2c6u0ckzfz59ig (click on download button at the top)
OR
1b) For Boost, download this xml file: https://www.box.com/s/o9folfrq00ee9p2qj5pv (click on download button at the top)
OR
1c) For Virgin Mobile, download this xml file: https://www.box.com/s/9itl21drpp84enqeszc9 (click on download button at the top)
2) Download and install "APN Backup & Restore" from the Google Play Store to your phone: https://play.google.com/store/apps/d...pRestore&hl=en
3) Convert the "APN Backup & Restore" into a system app by either using Titanium Backup, or simply use Root Explorer/ES File Explorer (root enable it) to move the APK from /data/app to /system/app.
4) Reboot the phone.
5) Launch the app, click on menu, then click on "Disable ICS Check".
6) In the main app menu, click on "Backup APNs". This will create a directory called "ApnBackupRestore" in your /mnt/sdcard.
7) Copy the xml file from step 1 to the /mnt/sdcard/ApnBackupRestore folder.
8) Go back to the main app menu, click on "Delete APNs" and confirm it.
9) Go back to the main app menu, click on "Restore APNs".
10) Choose the file you downloaded from step 1 and confirm it.
11) Reboot your phone.
12) Done.
Method 2 - (work around, doesn't require rooted phone)
1) Download and install Go SMS Pro to your phone from the Google Play Store.
2) Launch Go SMS Pro and skip through the intro message screens.
3) Skip the Go Chat Service offer unless you really want that.
4) Press Menu button on your GS3.
5) Choose Settings.
6) Scroll down the menu and choose Set default SMS program.
7) Press each entry in the list and put a check mark on "Use by default for this action" then choose Go SMS Pro. When both are done, press the back button on your phone.
8) Up on top, press "Advanced"
9) Scroll down the list and press "MMS Settings"
10) Scroll down the list and put a check mark on "Fill APN configuration manually"
11) Press "MMSC".
12a) Type in "http://mms.sprintpcs.com" - do not include the double quotes. Press OK button.
OR
12b) Type in "http://mm.myboostmobile.com" for Boost
OR
12c) Type in "http://mmsc.vmobl.com:8088/mms?" for Virgin Mobile
13) Press "MMS PROXY".
14) Type in "68.28.31.7" (Sprint & Boost) OR "205.239.233.136" (Virgin Mobile) - do not include the double quotes. Press OK button.
15) Press "MMS PORT".
16) Type in "80" (Sprint & Boost) OR "81" (Virgin Mobile) - do not include the double quotes. Press OK button.
17) Press back button on phone twice.
18) Send/receive a few SMS/MMS messages to test.
19) Done.

Works for Kit KAt (4.4) too
Hey,
Method 1 works for Kit Kat 4.4.1. I'm on a VM evo 3d with the CyanogenMod 11.0 VILLUMINATI Rom
The only difference is the app has to be moved to the /system/priv-app folder for it to be able to acquire the correct permissions.
I also did step 3) with titanium backup, not sure if it helped or not.
Cheers.
