[Sprint LG Optimus G] octhrope:
Notes:

[5-20-2014] - Updated 4.4 Apns to smaller format.

[11-1-2013] - Added Lite roms for both v7 and v8. v7 is 4.2 and 4.1, v8 is 4.3.

[10-30-2013] - Did some fiddling with making a universally accepted apn. I usually test everything before I upload it. That being said this is a test version I haven't used yet...

[9-23-2013] - New installer script courtesy of VoluntaryMan. Implemented as hotfix.

[9-20-2013] - Injecting the APNs into the rom before flashing seems to help. In my experience the system lost the apns after the first reboot and flashing them again made them stick.

[9-9-2013] - If its still not working, LGNPST the Teeny Original bin then the Teeny Alt Bin SLB Stack. Do one, the phone restarts; then do the other.

[8-27-2013] I am going to try to assemble a Frankenstein's Monster APN with every Sprint/Ting APN I can find and give that a shot too. So if the lights start to flicker you'll know why... :eek:

Unsuccessful so far...

[8-23-2013] update: Pulled the APN Stock files out of the ZVB rom... 3 different apns; looks like US, EU, KR.

ZVB Stock Deodex APNS

[8-23-2013]I'm going to try to pull the APN from a stock rooted phone at some point to compare with the clean, and custom ones. If anyone has one just pm a link. thanks.

[8-7-2013] Also am having some success with reflashing the jb modem. gives me the you've lost data error when im in the bathroom and loose data but not sending multiple sms messages.

[7-12-2013] If you use a Custom User Agent, (messages > settings > custom user agent) dont use iphone as Ting does not support them.

[7-2-2013] Some Ad Blocking programs will block mms. idk why the phones apns are not excluded from the shiz but adding your apns to the white list or removing the app should fix it.

manual fixes

fix 1

Open Voice Dialer, say "Open APN's"

Change all http://mms.sprintpcs.com to http://mms.plspictures.com

Select one of the profiles with the correct MMSC in it.

Reboot

fix 2

Open your root explorer, navigate to /system/etc and find apns-conf.xml

Copy it to another location

Change all instances of http://mms.sprintpcs.com to http://mms.plspictures.com

Copy and paste it back into /system/etc - overwrite old file

Reboot

I made this because mms wasn't working for me still. cant guarantee that this won't cause more problems since i have only tested it on my phone. (original ting apn plus proxies and ports)

While using octhrope modified ting apn v2

Setting a Custom User Agent TEMPORARILY Fixed the issue (messages > settings > custom user agent) Nokia N95.

did a bunch of testing and this is the only solution that was consistent. i suspect that Ting has no support for a generic android device on their network. after a couple days its back to not working.

fix 3

i did fix 1 but added the proxy and the port to all of the APNs (this might be wrong...)

proxy: 68.28.31.7

port: 80

reboot and sent picture.
