I saw this posted on another forum, and thought I'd ask the smart folks here if this is safe and if it works.

I've seen a lot of complaints about MMS on Sprint recently. This is supposed to fix it. Original post:


Currently Running 12/14 nightly and I was having MMS issues with the stock messaging app as well. BUT I have fixed the issue. I'm not sure why this information isn't as widely availible, considering it was easy to do and works perfectly.

Despite what android tells you when you download those third party apps to edit your APNs, it's actually quite easy to edit them yourself; using the voice dialer. Here's a little step by step guide that I whipped up from several sources so I can't really take any of the credit for this information:

APN Settings for Sprint running CM10

Function: Fixes MMS send and receive error. Also fixes Auto-Retreive!

Directions:
  • Go to Voice Dialer
  • Say "Open APNs" (Pronounce A-P-N)
  • Dialog will display open APNs, click it.

Now, create TWO new APNs by hitting the settings button on the bottom right of the touchscreen. Enter the information in the fields exactly like so (Please note that you must even enter the asterisks seen here, although you can leave the fields labeled as <not set> alone):

MMS Fix:

  • Name- Sprint
  • APN- cinet.spcs
  • Proxy- <not set>
  • Port- <not set>
  • Username- none
  • Password- ****
  • Server- *
  • MMSC-
  • MMS Proxy- 68.28.31.7
  • MMS Port- 80
  • MCC- 310
  • MNC- 120
  • Authentication Type- <not set>
  • APN Type- mms
  • APN Protocol- IPv4

Hit the settings button when you're done filling out the fields, and hit save.

MMS over Wifi Fix:

  • Name- Sprint
  • APN- mms_over_wifi
  • Proxy- <not set>
  • Port- <not set>
  • Username- *
  • Password- *
  • Server- *
  • MMSC-
  • MMS Proxy- 68.28.31.7
  • MMS Port- 80
  • MCC- 310
  • MNC- 120
  • Authentication Type- <not set>
  • APN Type- wifi
  • APN Protocol- IPv4

Save and reboot. Then you're done! Send an MMS to yourself to verify.
Someone telling me what to put in for a username and password make me a little nervous.
