How to Fix T-Mobile MMS on the iPhone

So I assume many of you have issues with your iPhones MMS on T-Mobile so here is the real solution (jailbroken or not)

If you are jailbroken download iFunBox (you can find it online)
If you aren't jailbroken download iBackupBot (you can also find this online)

Regradless if you are jailbroken or not you will need to download this file:

3. Navigate to private/var/mobile/Library/Prefrences

4. Drag in the com.apple.mms_override.plist you downloaded in the link above

5. It will replace the existing mms settings

6. Now reboot your phone, if you open settings-messages the MMS option will now be there

7. Now go to settings - general - network - cellular data network and change the MMS APN to epc.tmobile.com

8. Enjoy MMS
